Not at all. I know that Chinese censorship exists. You - or others, lost track since multiple people are involved here - are the one who’s trying to argue that US censorship does not exist, even in light of this TikTok ban.
Also, you probably don’t realize this, but censorship and moderation are many times two sides of the same coin - depending on the incentives and factors at play.
Censorship is very strictly defined as government’s doing. If this isn’t your definition, we aren’t even talking about the same things. I gave you a very concrete example with potentially serious consequences if you’re a Chinese national posting in China vs somebody getting deprioritized on one platform in yours.
