This is one of those tricky situations. On the one hand, Google, like YouTube, is a private company and is not bound by the 1st Amendment, and can fire people for any cause they like, including having politically unpopular (even if only unpopular with certain people) opinions or politics. On the other hand, communications companies like Google, Twitter and YouTube are so powerful, dominant and important to public discourse that when they decide to censor political opinions, there is not a whole lot that those so censored can really do about it. Could a million right wingers get together to buy up enough stock to repopulate the board of directors of these companies? Somehow I doubt it, but that might be the only way to keep these sort of companies from shutting down politics that’s right of far left.
