Correct, which is essentially what I said in my comment. But this article talked about free speech, and everytime this issue comes up, people start moaning that their right to free speech is being inhibited, apparently not realizing or caring that they have no such right on a privately owned and operated platform. That's why I brought it up.

It's too easy to proclaim every failure to shut up and listen to be censorship, sure, but Twitter is a corporation and its users are in a contract with it. Power granted and enforced by the state is at play here at least a little.

The problem with censorship is its function, not its form.
