Remember when he used to say he was a socialist? And literal morons believed him? It might have been when I realized how stupid and easily swayed most of the population is with obvious and blatant propaganda.
He also said he was a "free speech absolutist." Then he banned the guy who showed the publicly available info about the location of Elon's private plane. Then he banned the reporters who reported on that.
And that's how he started down the road to Twitter as it is now.
