Elon would just make the whole thing Elon friendly. He isn't going to make it a free speech haven. He's going to make it a haven for speech that Elon approves of.
Why do you think that? When he was asked if he was going to restrict information through Starlink, he said no, he wasn't going to restrict speech.
Why do you think on Twitter he would restrict it. That does not follow anything he has said or done regarding free speech.
