LOL, he was complaining about Twitter being too censored 4 years ago when he got cancelled by fellow leftoids:https://www.youtube.com/watch?v=GjtQODEe2vM
He probably threatened somebody with violence or rape if he got perma'd, honestly. Twitter is not a "hugbox", leftoids are just used to getting away with violent threats and harassment since communist pajeets used to control Twitter.
Musk is literally just enforcing the rules EQUALLY now. That means no more leftists posting death threats and antifa doxing people with impunity, while random conservatives get banned for saying there's two genders or whatever innocuous stuff. Shitlibs just pissed they don't have special protection anymore.
btw Musk never said it was going to absolute free speech like retards keep claiming; just "1st Amendment" type freedom so it's still illegal to call for violence or dox people.
