What anti-establishment stuff has he done? All of the negative things I see people mention about him are just general asshole behaviour rather than things that annoy the establishment.
He has multiple examples of using censorship himself to protect his companies. He denied a reviewer access to their vehicle, has stifled the speech of former employees of his companies, and has tried to silence a dissenter publishing publicly available data of his plane. You've fallen for the hype; Elon merely dresses himself in the flag of a free speech absolutist. He is exactly like the establishment in this regard: speech for me, but not for thee.
He has never advocated for removing speech from the public square or removing your right to hear speech. He didn't tell twitter to remove any account. He offered someone money (ie a private arrangement) to take it down and changed his mind. That's very different from forcibly revoking it and imposing censorship on the population.
You've fallen for a warped definition of free speech and censorship that is endlessly regurgitated by NPCs.
A world where Twitter is controlled by a self-interested Musk, while Facebook is basically aligned with the US political establishment, enables better dissemination of ideas than a world where Twitter and Facebook are both aligned with the establishment. Because Musk has notably different biases than the establishment, and either platform is sufficient for the purpose of giving nationally-relevant ideas adequate distribution.
(For this reason, in a world where Musk already controlled Twitter, I would oppose anything that increased his leverage w.r.t. Facebook, because yes, you're correct that Musk's biases are not harmless.)
Is he really though? You say this as if the twitter acquisition is over and done, and Free Speech has been saved by Musk doing......what exactly? So far we have so few details about what his plans for the platform are (or if he even has any) that everyone is free to project their own ideal outcome onto his actions. Let's wait a bit and see what happens before declaring him the savior of free speech.
