Exactly. If Twitter bans you, you're free to make your own Twitter or other speech platform. That is, the internet itself, not the private sites on it, is the public square.

If what you have to say is so revolutionary, surely people will be coming to your new site in droves to hear your amazing commentary they can't get on Twitter.

Except nobody actually cares about what these people have to say, or else they'd have already done so. Half the time you can bet it's some middle aged dude pissed off that he got reported for calling someone a slur or spreading 5G-mind-control-level conspiracy theories.
