I see X users these days as the frogs in the slow boiling pots.
I sense that some of the people who remain in X had some rationales. Those who liked what they saw in terms of abuse or bad behaviour would naturally stay for more.
Perhaps others felt their voices would resist mis/disinformation, or contribute to greater discussion. But, those who chose to stay, regardless of reason, ended up conditioning themselves to receive or disregard abuse beyond all sense.
Now the platform clearly violates its members, and Musk has once again affirmed publicly that he is a white supremacist. Users - including government accounts - who remain have unwittingly become members of an extremist, white supremacist website that peddles CSAM materials.
I think it's the stuff of movies, and something a villain, like the Joker, would have done.
