Apples and oranges. I think the doxxing policy makes sense. It's absolutely not okay posting people's real-time locations, especially for famous figures who are already targets.
I don't hear anybody criticizing the policy. Because it is right. Instead people are attacking Elon's past promise, as it is the only thing they can attack.
So maybe "absolute" free speech is not a very good idea after all. What matters is good moderation.
