Ordinary users would be banned for the stuff he said. No question about that.

Twitter is already giving the president a lot of leeway in what he can say.

Banning someone for violating the EULA is not political censorship.

Donald Trump is a user on the platform who agreed to the terms of service like everyone else. Private firms have the right to terminate the account of people who breach those terms, which he has done repeatedly, which is why he should have been banned a long time ago.

If he wants special privileges and communicate as the president he can use the official communication channels.

It seems to be increasingly lost on the US government (and people) that the presidency is an institution, not a person. If Donald Trump starts a barfight in a nightclub he can get arrested like everyone else.

It isn't but neither is politicians spreading lies and misinformation.
