Elon has interacted frequently and positively on Twitter in the last few weeks with alt-right figures like Ian Miles Cheong and Andy Ngo, e.g. agreeing that the slogan "hands up, don't shoot" is somehow a "lie", and retweeted a weird homophobic conspiracy theory about Paul Pelosi almost immediately after completing the acquisition. I don't think there was good (public) reason to believe these were his politics a year ago, but it seems that he's either shifted or made a deliberate cynical decision to court them to build the userbase. (And little about the Twitter acquisition has seemed that planned.)
