As with so much of what happens at X, there is significant confusion about the policy as the company’s rules seem to change based on the whims of Musk rather than a considered process.
Here is what I assume happend:
Elon, desperate for approval from his “fans” personally changed this, because almost all the people left on twitter that engage with him are “right-wingers”. And they dont want to be held accountable for being vile garbage.
And so they, like the most fragile of snowflakes, started to whine about having to follow basic rules of human decency for once in their online existence, making them deeply uncomfortable.
And Elon followed suit, because these are the only people he has left now. People who exploit him for his position and clout, just as he exploits them for small ammounts of dopamine, when they applaud him for making the worls worse again.
