Considering Twitter has banned many other people and celebrities why couldn't they decide to suspend the account of President Donald Trump? If Twitter does not suspend his account does it mean Twitter endorses what Trump is saying? Does Twitter even have the legal authority to suspend the account of the President?
These are all interesting questions particularly from a libertarian perspective. Twitter is a company owned by it's shareholders and I don't see why any account they choose could not be removed or banned legally. Of course banning the President could have some negative consequences which could explain why it doesn't happen but we do know Twitter believes in censorship for everyone who is not the President.
