Twitter, Amazon, Facebook face fallout from taking action against Trump and his supporters

Twitter's decision to remove Trump's account, citing the potential that his corrosive rhetoric might incite additional violence, precipitated a sharp drop in the company's shares, which fell by more than 6% by midday Monday. Twitter also braced for a potential protest outside its San Francisco headquarters, a demonstration that the president's supporters have sought to organize on pro-Trump forums in recent days.

Amazon, meanwhile, faced a new lawsuit from Parler, an alternative social network that had become a haven for Trump's backers. Amazon Web Services, which provides cloud computing services, suspended its relationship with Parler starting Monday in a move that removed it from the Web - prompting Parler to allege that Amazon had acted unlawfully. Amazon shares also dipped slightly by afternoon.

The flurry of activity reflected the still-intensifying clash between Washington and Silicon Valley in the days since Trump's incendiary comments about the 2020 election helped spark a riot that forced the U.S. Capitol into lockdown and left five people dead.

Late Friday, Twitter banned Trump, citing two tweets, including one that said he is not planning to attend President-elect Joe Biden's inauguration. Facebook earlier in the week said it was suspending Trump for at least two weeks. Sheryl Sandberg, the company's chief operating officer, said in an interview with Reuters on Monday that there are "no plans to lift" the ban.

On Monday, Facebook announced additional policy moves, including a new crackdown against posts that reference "stop the steal" - a rallying cry for Trump and others that have sought to delegitimize the outcome of the 2020 race. Before Biden's swearing-in ceremony, Facebook said it also would maintain its pause on political ads and aim to monitor its service more aggressively for harmful content as it seeks to "stop misinformation and content that could incite further violence during the next few weeks," executives said in a blog post.

Other tech giants have joined Twitter and Facebook in taking action against the president and his allies in recent days amid mounting political tensions in the United States - and growing fears about deadly violence still to come. That includes Parler, which Apple and Google removed from their app stores in a move that further constrained the right-leaning service's reach. Joining Amazon, the tech giants each say Parler has not properly policed its platform for violent threats, an accusation Parler denies.

Trump responded to the Twitter ban with a statement late Friday promising to seek an alternate social network - or build one of his own - in an attempt to get around the vast digital blockade. Trump is expected to spend the final days of his presidency attacking Silicon Valley over allegations of censorship, according to a person familiar with the matter who spoke on the condition of anonymity to describe internal White House planning.

"We will not be SILENCED!" Trump said in the statement, which he previously had tried to tweet from the president's @POTUS account before Twitter blocked it.

Twitter and its fellow tech giants deny the charges of censorship. The White House did not immediately respond to requests for comment.

Trump's supporters, meanwhile, took to a forum sympathetic to the president, called TheDonald.win, to express their own displeasure. Some users even called for the execution of House Speaker Nancy Pelosi, D-Calif., and other political figures, according to posts reviewed and compiled by the SITE Intelligence Group, which tracks online extremism. Others encouraged a protest at Twitter's headquarters, though no such crowd had formed at the company's offices by midday Monday.

"Maybe the hq should be burned down when everyone goes," wrote one user on a widely trafficked thread.

A wide array of pro-Trump online communities, including TheDonald, had teemed with similar talk ahead of the riot at the Capitol last week - and since then they have glorified the violence that took place in Washington. The National Guard is set to deploy up to 15,000 troops during the inauguration in response to the heightened threats.

As users online lashed out, Parler filed a new lawsuit against Amazon that alleges the company acted anti-competitively, and hypocritically, in choosing to suspend it. Twitter also hosted violent threats, according to lawyers from Parler, who asked a judge to grant a temporary restraining order to prevent Amazon "from shutting down Parler's account."

"Doing so is the equivalent of pulling the plug on a hospital patient on life support," the lawsuit contends. "It will kill Parler's business - at the very time it is set to skyrocket."
