There are nicely cataloged lists elsewhere in this thread for you to no true Scotsman

I for one, if you made me pick an example, would point to his treatment of Vernon Unsworth.

He insulted Vernon, but did not censor him. So what is your evidence that Elon Musk censors people?

he tried to 'cancel' him by calling him a pedophile.

There are varying definitions of 'censorship' floated in this thread. A lot of people in this thread who are defenders of Musk are willing to apply the label censorship to 'canceling people'...or at least when certain people get push back. If we take their definition at the word, if we take it as honest, then it is reasonable to apply to his own actions.

vis a vis, by the definition of censorship floated in support of Musks purchase, he censored Vernon.

Do I buy that definition? no...but...I don't think 'cancelling' is censorship, I think its just another form of free speech thats given a hostile label to bound free speech in a hierarchical way.

Otherwise, and its worth noting this actually highlights the subtext of the overall conversation, there are two definitions of censorship being applied by some people - a broader one to speech they like, and a narrower one to speech they don't.
