Starting a new thread because I think the other one (OK Let's do this: who thinks social media's recent bannings are first amendment violations?) asked the wrong question, but there was interesting discussion developing on the question of freedom of expression.
Banning incitement to violence, or anything else that’s actually illegal, should not be a problem. But going further and banning political speech (and that includes ‘hate speech’ when it can be defined so broadly) is a freedom of expression problem. I object to Twitter or Google deciding what’s true or false, or right and good, even more than to the government doing it. At least people get to vote for the government. And as for finding a different platform, we’ve seen how hollow that option is with the demise of Parler.
Like I said, I think this is a great opportunity to do something about the monopolies, now when conservatives are at the sharp end of the censorship battle. The question is whether anyone in government shares your objection to monopolies and will take advantage of the opportunity. Personally I doubt it.
