How do you judge this rule by itself, on merit? Would you have judged this rule differently, had Musk not be attached to it in any way?
The point being, you fail to separate actions and outcomes from the person. Since you already decided that he's an asshole and this narrative cannot be broken.
Had another person come up with this rule, then it would be seen as a cool, progressive anti-doxxing measure. Wonderful.
If you don't see an issue with this type of clouded thinking, then you've been fully indoctrinated in Twitter discourse.
