I don’t find a problem with a joe filtering out what he doesn’t want to hear, I however have a problem with some platform growing so big and establishing itself so that if you or your business isn’t on it, you may just as well not exist at all, and then booting people out on a whim. Come to think of it, for an effective censorship to exist, you don’t really need a hostile government, if private entities that affect your life in a big way are just as big, if not bigger.
