Now not only can Elon say as he pleases, but he can do so knowing he and his associations will never be punished on one of the most influential platforms ever to exist. As per usual, his genius being put on display along with some of his opponents and dissenters misplaced fearful acknowledgement.
It's not that easy though. Twitter can't host itself; someone else has to do it. IIRC hosting providers have shown their willingness to stop hosting services they find problematic, and finding a new hosting provider for a service the size of Twitter might not be simple. This should provide Musk some freedom if he so desires, but by no means does this guarantee absolute freedom (even within legal limits, whatever that means for an internationally provided service).
