Those are some, but the way you're phrasing that makes it sound like you are under a strange impression that it's only ones carried over from before! Also, you seem to imply his structural changes to Twitter made the overall handling of such better somehow, which rather seems to be roughly the opposite of the truth.
There are a lot of other similar reasons for censorship that are normally considered quite justified and reasonable, too, incidentally! Terrorism stuff is an obvious one. As it so happens, that's honestly not especially far in concept from the Brazilian attempted violent coup stuff that Musk seems to have chosen to try to protect.
With that noted, though, there are also things like... his "cis" suspensions policy, stunts like how he chose to effectively hand moderation decisions over to a bunch of very... politically motivated right wing people, and directly stated his intention to personally get involved in banning left wing accounts. All those are examples of things that directly undermine or refute the narrative you're trying to sell here. Adding in his anti-free speech lawsuits and actions to remove transparency just make things worse for that narrative.
