Platform businesses aren't public commons, they're businesses, which means they're free to pick-and-choose winners and losers arbitrarily, if they so desire.

OTOH if controversial content creators want the freedom to publish, fundraise and engage audiences, it behooves them to prefer audience-funded, almost-anything-goes platforms that will cater to all forms of legally-protected speech. Otherwise, they're asking for trouble in the form of arbitrary silencing.

Cultural fascism, whereby people are censored because their legal speech is unpopular, is a path towards totalitarianism and civil war.
