Problem is, community notes are/can be weaponized by groups of people to lower visibility of a dissident thought that is not incorrect, and although a note was not necessary.
In France, it seems like the same fake-fact-checkers that used to harrass people about covid have now the option to write community notes, and they do it in a coordinated way. You can just tell by their methods and the community note content.
➡️So community notes are indeed useful when there is no abuse or weaponization, or else it ends up being another new form of censorship.
