It's not opinion or votes all the way down. The corrections have to be referenced. So if someone is misrepresenting a fact, it will be community noted and votes will accumulate as all that remains to do is verify the referenced source.
It really is. An unreferenced note may be voted up; a well-referenced one may not. There's certainly no requirement you even click the references to see if they say what's claimed. A misrepresented fact may be noted, and it's certainly not synchronous.
