Yes. It's censored some. For example, when Russian disinformation has been cracked down on, "conservatives" that were completely indistinguishable from Russian disinformation operatives and bots have been caught up in that, to what *should* be no one's surprise - or outrage at anything other than the fact that US citizens are spreading Russian disinformation, whether intentionally or unintentionally. Various other cases among roughly the same lines have happened, too.
Quite frankly, "conservatives" *should* be doing some serious introspection, rather than making inane complaints about censorship. That's assuming that they are well-informed, law-abiding, and patriotic citizens. The complainers can generally be assumed to have failed to possess one or more of those qualities.
