No, rational criticism of the world’s richest man and his business decisions is not “hate speech”. Hate speech is when you say “Jews are the scum of the earth” or “faggots should burn in hell”. Because Jewish people and gay people usually don’t have 400 billion dollars handy to defend themselves against attack, and because they are attacked as a class, not individually, they can’t sue for defamation as Musk can if someone says something untrue and harmful about him. It’s ludicrous that you claim to support free speech but you attack this expression of that very right as “hate speech”.
