Twitter on Wednesday placed restrictions on President Donald Trump’s statement regarding Washington rioters due to “risk of violence.”

“This claim of election fraud is disputed, and this Tweet can’t be replied to, Retweeted, or liked due to a risk of violence,” the company wrote under a tweet by Trump that directs users to a page that says “there is no evidence of widespread voter fraud in the 2020 U.S. presidential election.”

In his recorded statement, Trump falsely claims that the election “was stolen” before asking rioters to go home.

Earlier, the company said it would “take action” on any content that calls for violence in regard to the riots happening in Washington.

“Let us be clear: Threats of and calls to violence have no place on Twitter, and we will enforce our policies accordingly,” a spokesperson for the company said in a statement.

Additionally, the company said it will significantly restrict engagement with tweets labeled with its Civic integrity policy, which does not allow Twitter users from using the service to manipulate or interfere with elections or other civic processes.

“We are also exploring other escalated enforcement actions and will keep the public updated with any significant developments,” the company tweeted.

The statement comes as rioters in support of President Donald Trump breached the U.S. Capitol, forcing lawmakers to evacuate.

Calls are mounting for Twitter to shut down the president’s account or take other extreme action. Chris Sacca, an early investor in the company, tweeted “You’ve got blood on your hands, @jack and Zuck,” referring to Twitter CEO Jack Dorsey and Facebook CEO Mark Zuckerberg.

“For four years you’ve rationalized this terror. Inciting violent treason is not a free speech exercise. If you work at those companies, it’s on you too. Shut it down.”

The ADL issued a statement calling on social media companies to suspend Trump’s accounts “ASAP.”

There are ways to automatically delete your old tweets on a recurring schedule so that it’s harder for people to find some of the silly things you may have said in the past. It might be helpful if you’re applying to new jobs, planning to run for office or just want to keep on top of the things you’ve said online.

There are still plenty of ways to find old tweets, most stuff online is archived, but at least people browsing through your Twitter feed won’t be able to see your random comments to friends, silly one-off remarks or something really terrible you said that you shouldn’t have.

I recommend TweetDelete.net. But sometimes free tools like this vanish and you might have to find another one. The first option I used to delete my tweets for a few years no longer exists, for example, and Twitter itself doesn’t have an option to delete your tweets in bulk. That means you have to turn to third-party tools.

Anyway, let’s get going, here’s what you do.

• Go to TweetDelete.net in your web browser.
• Tap “Sign in with Twitter” and log in with your Twitter username and password.
• Choose “Authorize App.” This gives the app permissions to see your tweets (it needs to in order to delete them), follow and unfollow accounts for you, update your profile, post and delete tweets, manage lists and more. It’s a lot of permissions, but TweetDelete says it only asks for it in order to do the deleting and that it doesn’t sell any data.
• Now confirm how far back you want to delete. I choose all tweets older than one month, but there are a variety of options.
• You can also choose to delete tweets only containing certain phrases.
• Finally, you’ll set TweetDelete to perform the action just once or every few days. I recommend picking “automatically every few days” so that it constantly deletes older tweets.
• Confirm you agree to the terms and understand you can’t get deletes tweets back.

That’s it. Now TweetDelete will run through your old tweets and show a progress bar as it moves back through your timeline and removes your old posts. I had about 2,300 and it took a few minutes.

A handful of Microsoft employees spoke out against the software company’s campaign contributions on Twitter after Brad Smith, Microsoft’s president, said in a Twitter post on Monday that the company is in favor of a peaceful transition of power to President-Elect Joe Biden.

The tussle concerns the Microsoft Political Action Committee, known as MSPAC, through which employees can contribute money that goes to state and federal candidates and to other committees. MSPAC’s first contributions on file with the U.S. Federal Election Commission date to 1988, two years after Microsoft’s initial public offering. The group has long given to both Democrats and Republicans.

The flare-up came days before the Jan. 6 hearing during which Congress will gather to approve the Electoral College outcome of the 2020 presidential election, in which Biden surpassed incumbent Donald Trump. Since the election, Trump has launched multiple unsuccessful attempts to challenge election results in several states where he lost. In a phone call Saturday,Trump pleaded with Georgia’s secretary of state to “find” the president enough votes to overturn Biden’s win in the state, according to recordings released after the call.

Eleven Republican Senators have aligned with Trump and said they would attempt to delay the certification of votes on Wednesday, citing allegations of fraud and irregularities in the 2020 election for which they provided no evidence and which have been rejected repeatedly by courts around the country.

On Monday, Smith signed a letter insisting that Congress accept the Electoral College results.

One Microsoft employee, Jake Friedman, responded to Smith’s call on Twitter by asking if Microsoft should stop giving to people who wish to get in the way of a smooth transition. Friedman published a screenshot showing details of a $2,000 donation to a committee backing Jim Jordan, a Republican U.S. representative from Ohio who sought and won re-election in November. In December Jordan told Fox News he was in favor of having “a real debate on Jan. 6.”

Microsoft employee Mike O’Neill thanked Friedman for the tweet on Tuesday and said he had requested a cancellation of future donations for MSPAC.

Brandon Paddock, another employee at Microsoft, suggesting discontinuing MSPAC or blocking MSPAC contributions to people who get in the way of democratic principles, which Smith had mentioned in his tweet.

Smith did not address the criticism.

“We weigh a number of factors in making political contribution decisions, and will consider this and other issues in making future contribution decisions,” a Microsoft spokesperson told CNBC in an email on Tuesday.

The question of how MSPAC contributions fit in with the ideals Microsoft espouses, such as ensuring privacy, came up in November, after journalist Judd Legum pointed to a $2,500 MSPAC contribution to a group supporting the re-election of Republican Sen. Lindsey Graham of South Carolina. In June, Graham had introduced legislation that would help law-enforcement agencies access encrypted data. Graham was re-elected in November.

Microsoft employees picked up on Legum’s message.

One of them, Justin Schoen, said he would reconsider his contribution to MSPAC.

“We recognize that to make progress on the issues that matter to our customers and to our business, we must engage with candidates and officeholders who hold a range of views,” a Microsoft spokesperson told CNBC at the time. “Given the breadth of our policy agenda, it’s unlikely we’ll agree on every issue, but we’ve learned that engagement—even when individuals hold different positions—is an essential part of achieving progress.”

After reports speculating about Alibaba founder Jack Ma’s whereabouts, CNBC’s David Faber reported Tuesday that the billionaire is not missing, according to a person familiar with the matter. Instead, Ma has been laying low for the time being, Faber reported.

Outlets including The Wall Street Journal reported this week that Ma has not been seen in public since he spoke at a forum in late October where he appeared critical of China’s financial regulators.

Shortly after, Ma’s Ant Group saw its record-setting IPO suspended by stock exchanges in Shanghai and Hong Kong. Ma and two Ant Group executives were summoned and interviewed by regulators in China, the China Securities Regulatory Commission said in a November statement.

GUANGZHOU, China — Apple iPhone maker Foxconn has signed a deal with Chinese electric carmaker Byton to help produce its first vehicle.

The move marks a big push by Foxconn into auto manufacturing as it tries to diversify its business beyond just assembling consumer electric products.

Foxconn, which trades Hon Hai Precision Industry Co. in Taiwan, saw its shares jump over 4% on Tuesday after they closed over 8% higher on Monday.

Byton, Foxconn and Nanjing Development Zone signed a strategic cooperation framework agreement on Monday to jointly produce Byton’s M-Byte SUV by the first quarter of 2022.

Foxconn will provide its expertise in advanced manufacturing technology, operational management experience and will share industrial resources, according to a statement from the companies.

The agreement could provide a lifeline for Byton which first revealed the M-Byte in 2018 but has since struggled to ramp up production. The Nanjing, China-based company had to suspend production in July and undergo a reorganization after the coronavirus pandemic hurt the business.

For Foxconn, the deal is a way to diversify its business. Last year, Foxconn launched a set of tools that would allow a company to design large parts of an electric car that would be manufactured by the Taiwanese firm. These tools include a chassis as well as software for the vehicle.

Foxconn has already been supplying automakers including Tesla with specific components.

China’s electric vehicle market continues to show strong growth. Electric car start-ups Nio, Li Auto and Xpeng each announced in the last few days that deliveries surged in 2020 to close out the year with new monthly highs.

More that 200 Google employees on Monday announced that they’ve come together to form the Alphabet Workers Union amid increasing disagreements with company executives.

News of the union was published in a New York Times op-ed written by two employees, Parul Koul and Chewy Shaw, who serve on the board of the Alphabet Workers Union as executive chair and vice chair, respectively.

Koul and Shaw said they have signed cards with the union Communications Workers of America, a group that represents workers from companies like AT&T and Verizon. They said more than 226 employees have joined the union. The union will be open to all Alphabet workers, they said, including temps, vendors and contractors. Alphabet has several subsidiaries including Google, YouTube and the self-driving car company Waymo. Alphabet has more than 130,000 employees worldwide.

“For far too long, thousands of us at Google — and other subsidiaries of Alphabet, Google’s parent company — have had our workplace concerns dismissed by executives,” the two said in the op-ed. “Our bosses have collaborated with repressive governments around the world. They have developed artificial intelligence technology for use by the Department of Defense and profited from ads by a hate group. They have failed to make the changes necessary to meaningfully address our retention issues with people of color.”

Tensions have risen between employees and executives in recent years. In 2018, Google employees wrote a letter to CEO Sundar Pichai asking him to end a partnership between Google and the Pentagon. Later that year, employees around the world staged a walk-out to protest the company’s handling of executives accused of sexual misconduct, including a $90 million exit package for former Android lead Andy Rubin. Protests were also held in in 2019 to support two employees who were being investigated for retaliation claims. Most recently, employees created a petition to support departed AI researcher Timnnit Gebru, who said she was fired over a research paper dispute.

In a statement to CNBC, Kara Silverstein, Alphabet’s director of people operations, said the company supports workers’ labor rights, but didn’t directly address any of the group’s complaints.

“We’ve always worked hard to create a supportive and rewarding workplace for our workforce. Of course our employees have protected labor rights that we support. But as we’ve always done, we’ll continue engaging directly with all our employees,” Silverstein said in the statement.

In the op-ed, Koul and Shaw alleged that Alphabet punishes internal critics of the company on topics important to the public, like the antitrust lawsuits against the company. They also said Google executives consolidate their power at the cost of minority groups like Black, trans, queer and disabled workers.

“Our union will work to ensure that workers know what they’re working on, and can do their work at a fair wage, without fear of abuse, retaliation or discrimination,” Shaw and Koul wrote.

Airlines are joining the fight against the coronavirus. 

The long wait for a vaccine may be over, but distributing it to the 7.8 billion people around the world is the next big challenge. In the U.S., both the Pfizer–BioNTech and Moderna Covid-19 vaccines require two doses that will eventually need to reach the nation’s roughly 330 million people.

Even though shipping is only one part of the journey, it’s a critical step. DHL and McKinsey estimate vaccinating the world will require up to 15,000 flights. In the U.S., airlines have stepped up to become a crucial part of the supply chain alongside logistics giants like UPS, FedEx and DHL. 

American Airlines, Delta and United have been preparing since the summer and jumped into action hours after vaccines were approved for emergency use in the U.S. 

Airlines carrying pharmaceuticals and vaccines is not a new idea, but the scale and speed at which the Covid-19 vaccines must be delivered makes it a more complicated endeavor.

Alyson Watson had an important message for her team. It was May 1, six weeks after the coronavirus pandemic forced employees into isolation. Her company, Modern Health, was busier than ever.

Watson, 30, started Modern Health three years earlier to help expand the availability of mental health services with virtual and web-based programs that companies could offer to their staff. While demand steadily picked up prior to 2020, the onslaught came in March and April as businesses saw the early strains of the Covid-19 crisis on their workers.

Initially, Watson tried rallying her employees, indicating that this was their time to shine, and that “we need to go 110%,” she told CNBC in a recent interview. But given the anxiety she started experiencing personally with the new remote reality, and knowing that times were even harder for people with kids, Watson realized she needed to convey to employees that their own mental health comes first.

In a companywide Slack message at the beginning of May, she admitted that the Zoom calls have “worn me out a bit” and said that she was finding ways to take care of her mental and physical health.

“Whether that is eating healthy, getting exercise, turning OFF technology for some time in the day, meditating, spending time with your kids, your significant other, your family — now is the time to do it,” she wrote. “Commit to it. The team needs you to commit to it. For yourself and for each other.”

Watson said it was like flight attendants reminding passengers that, in the case of an emergency, they need to put on their own oxygen mask before assisting their kids. For Modern Health, the emergency was just beginning.

As weeks out of the office became months, Modern Health’s employees, like its growing roster of customers, faced an exhaustive list of issues related to health, money, family and school. Watson went so far as to tell them that she was regularly seeing a coach, a therapist and a couples therapist.

“For the first time it really became front and center for us that we need our own mental health to deliver on a successful mental health experience,” she said, in the interview.

Modern Health, which is based in San Francisco, combines virtual one-on-one access to therapists and coaches with digital content like guided meditations. In mid-December, the start-up raised $51 million in a round that valued it at over $500 million. Headcount tripled in 2020 to over 140 people, revenue has multiplied by 25 times in 18 months and the customer base has doubled since March.

Customers including Electronic Arts, Pixar and Lyft pay a monthly fee on a per-employee basis.

Throughout 2020, the pandemic was the biggest source of employee angst, Watson said. But it was far from the only one. Racial injustice issues took centerstage in June after the killing of George Floyd by a police officer sparked nationwide protests. And November’s presidential election caused plenty of stress and anxiety.

“One of the things we’ve seen this past year is mental health has become a top priority for every employer across the board across every industry,” Watson said. She added that the average user is spending 50% more time on the app than before the pandemic.

Even before Covid-19, Modern Health and other digital mental health companies like Lyra Health, Talkspace and Ginger were gaining traction, because traditional counseling is expensive and there’s a nationwide shortage of trained therapists.

While telehealth has soared during lockdowns for obvious reasons, there’s a wider swath of people who are benefiting from mental health coaches for issues like loneliness, relationship challenges and job-related stress. They don’t all require hour-long sessions. Sometimes a quick text chat does the trick.

“There are not enough therapists on planet Earth to meet the demand we’re seeing,” Watson said.

In between talking to new customers like Clif Bar, Zendesk and TripActions, recruiting talent and working on new products and partnerships, Watson said she’s focusing on exercise and eating well. She told employees she was carving out at least 15 to 30 minutes five days a week for workouts, along with her therapy and coaching sessions.

“While I’m nervous to share all of this, I feel obligated to feel vulnerable knowing that my team has my back,” she wrote.

It’s a message she returned to repeatedly in the subsequent months.

“Being a mental health company doesn’t mean it’s not really hard,” she told CNBC. “You’re still a start-up. There’s a lot of stress and burnout that comes with the territory.”

WATCH: Covid has led to a ‘dramatic increase’ in global mental health woes

Tech’s biggest companies just wrapped up a huge year.

The seven most valuable U.S. technology companies — Apple, Microsoft, Amazon, Alphabet, Facebook, Tesla and Nvidia — picked up a combined $3.4 trillion in market cap in 2020, powering through a global pandemic and broader economic crisis.

Between continued optimism over iPhone sales, Microsoft’s growing Teams collaboration product, Amazon’s ongoing control of e-commerce and the strength of Google and Facebook’s online ad duopoly, Big Tech was neither slowed by Covid-19 nor the rising number of investigations into its dominance.

Tesla’s wild rally served as the biggest surprise.

The stock climbed almost ninefold this year, lifting the electric car maker’s market cap from $76 billion at the beginning of the year to $669 billion at Thursday’s close. Despite initial factory closures due to the pandemic, Tesla bounced back to deliver a record number of vehicles in the third quarter.

This month, Tesla became the largest-ever addition to the S&P 500, joining the index with the fifth-heftiest weighting after turning in five straight profitable quarters.

Meanwhile, chipmaker Nvidia more than doubled in value in 2020, closing with a market cap of $323 billion, making it the seventh most valuable tech company and number 16 overall in the U.S. Nvidia’s graphics processors for gaming devices have been flying off the shelves so quickly that the company has struggled to keep up with demand.

Nvidia’s chips are also gaining traction in the data center, where enhanced workloads require faster speeds. In September, Nvidia agreed to buy mobile chipmaker Arm Holdings from SoftBank for $40 billion, the second-largest deal announced by a U.S. tech company this year. However, Chinese regulators could still block it.

By far the biggest increase in market cap went to Apple, which jumped by almost $1 trillion in value, thanks to its stock climbing 81%. Amazon, which benefited from growth in its consumer and cloud-computing business, rose by $710 billion. Microsoft picked up $480 billion, while Alphabet gained $268 billion and Facebook $193 billion.

The gains are clearly reflected in the ranks of the richest people. Amazon’s Jeff Bezos is the wealthiest person in the world, followed by Tesla’s Elon Musk and Microsoft co-founder Bill Gates. Facebook CEO Mark Zuckerberg is fifth. Also in the top 10 are Google founders Larry Page and Sergey Brin and Microsoft ex-CEO Steve Ballmer.
