This analogy only makes sense if Twitter had a virtual monopoly on online speech in the same way that a company town has a monopoly on access to shared physical spaces.The fact that you’re reading this on an alternate social media platform demonstrates that’s clearly not the case. It’s hysterical to suggest that getting booted from Twitter is the online equivalent of being imprisoned in your own home.
It’s frustrating that Twitter isn’t more transparent about its banning/unbanning policies, but there’s no evidence it has a constitutional or legal obligation to do so. An ethical obligation? Maybe, but that’s up to Twitter. If users get fed up with it, user will vote with their eyeballs, Twitter will go the way of MySpace and users and their speech will move somewhere else.
