Presumably you liked the fact checkers before because they were of the same political persuasion as you. Now that Trump is in power would you prefer if Musk/Zuckerberg placed right wing fact checkers in place and punished any opinion which is outside of the platform's Overton window?
Musk removed picking fact checkers and replaced them with community notes. Zuckerberg says he'll do the same. Isn't that the societal accountability that you want?
