He certainly has not demonstrated that he's in favor of free speech. He did restore a bunch of accounts - mostly far right trolls - and banned a bunch of others. It's not like Twitter wasn't a cesspool before, but he managed to make it worse while blaming the previous regime for being asleep at the wheel. The guy who used to be in charge of content moderation recently had to flee his home after Musk suggested Twitter had been turning a blind eye to child abuse and his army of sycophants went on the warpath. This is after he fired the entire team responsible for dealing with that garbage. He accuses companies who are cutting back advertising of being against free speech. The guy is a straight up cyber bully. Anyone paying attention has known that for years. Free speech only matters when it's his own free speech.
