"For example, Scott Adams was banned from twitter"
--"I would regard it as treason"
lol no. He knows about as much about the Constitution as his favored candidate knows. Treason is a capital offense from the constitution, one of few, and this is not that. It's doesn't even violate the First Amendment, although it might be censorship.
I don't know anything either way about the trueness of his claims of being shadowbanned by Twitter, but it's not treason, and it's not a First Amendment issue, and it's not even remotely illegal. If you don't like their platform, don't use it.
It'd be pretty funny if Scott was able to prevent the sale of Twitter, though.
