And if you actually open the App Store rules link, it says "To prevent abuse, apps with user-generated content or social networking services must include [...] The ability to block abusive users from the service". As in, X needs the ability to ban users from X.
It seems to me like community notes are a great way to push whatever reactionary narrative someone manages to cook up when they oppose the person tweeting / the topic at hand.
It's a good way to push any "status quo" narrative. Community Notes present themselves as true, so naturally people don't question the things that they link to. I've seen posts before where many incorrect Community Notes come and go on that same post.
It is the standard internet psychology: someone says something that seems dubious or they are generally a dubious person, a "sensible" person or agency (Community Notes) comes along with a lot of popular support to offer a rebuttal, a vast majority then assume the latter is true without bothering to check. The act of professional sounding, assumedly popular rebuttal, given with sources, is enough for people to accept a random thing as a fact. Almost no one checks the sources.
