You're forgetting how the Twitter acquisition actually went. Almost immediately after the contract was signed he started trying to weasel out of it with various absurd excuses. He only stopped trying to violate the purchase contract once it became clear he was almost certain to lose in court.
He is breaking the law, full stop. Sorry but you don't get to do that in a Republic without consequence. Process matters when it comes to regulation, because without it you get unchecked power and tyranny.
If pre-Musk twitter was in the hands of censorship, what is it now? By all accounts it is a bot-infested echo chamber for his own bizarre obsessions where dissent is quickly stamped out.
