Twitter said on Friday its suspension of Trump’s account, which had 88 million followers, was due to the risk of further violence following the storming of the U.S. Capitol last week.
But the move drew criticism from some Republicans for quelling the President’s right to free speech, and European Union Commissioner Thierry Breton said the past week’s events likely heralded a new era of heavier official control.
That concerned financial investors, who worry that Twitter will be more exposed to any push on regulation than its bigger rivals Facebook Inc or Google and YouTube-owner Alphabet .
Other social media platforms including Facebook have issued similar bans on Trump, but the fall of as much as 12% in Twitter shares was much heavier than for any of its peers.
“Trump has a very high and loyal following and a lot of those eyeballs will go away if Trump is permanently restricted from posting,” said Andrea Cicione, head of strategy at brokerage TS Lombard.
U.S. media also reported San Francisco police were bracing for a possible protest by pro-Trump supporters outside Twitter’s headquarters on Monday.
The police department said in a statement that it was “aware of the possibility of a demonstration” and it would “have sufficient resources available to respond”.
BIG TECH POWER
Friday’s move, accompanied by suspensions for some of Trump’s supporters, was the first time Twitter had banned a head of state, and Republican lawmakers denounced its decision as an attempt to stifle conservative voices.
Apple Inc, Alphabet and Amazon.com Inc also suspended Parler, a pro-Trump app where users have threatened more violence, from their app stores and Web-hosting services, effectively making the service inaccessible.
“These moves, whether you consider them justified or not, could well see them lose further users if they become seen as arbiters of what is considered politically correct or acceptable,” said Michael Hewson, chief analyst at CMC Markets UK.
U.S. President-elect Joe Biden has been quoted as criticizing the “overwhelming arrogance” of the tech sector’s leaders and analysts expect more legal moves to curb their power over the next four years.
EU Commissioner Breton said the sea change in regulation may prove comparable to the global crackdown on terrorism after the attacks of Sept. 11, 2001. “The fact that a CEO can pull the plug on POTUS’s loudspeaker without any checks and balances is perplexing,” he wrote in a column for Politico.
“It is not only confirmation of the power of these platforms, but it also displays deep weaknesses in the way our society is organized in the digital space.”
