It's a welcome move as this "fact checkers" thing was doomed to fail, mostly because "who decides what the truth is, and who fact checks the fact checkers?".

Sad thing is, this move isn't motivated by Mark Zuckerberg having a eureka moment and now trying to seek out the truth to build a better product for human kind.

This move is motivated by Mark's realizing he is on the wrong side of American politics now, being left behind by the Trump/Musk duo.
