I wouldn't be surprised if it's even worse than he's describing, but at the same time, it's not like we didn't expect it. The platform has seen a colossal influx of bigots, and all kinds of completely unhinged people, because Elon has clearly shown that he's okay with them posting what they want
I just don't get what's so problematic with casual bigots when one can encounter Turkish and Azeri Nazis (and bots) in numbers and nobody is really trying to fight them, on any platform.
But then nobody's trying to fight them IRL.
In terms of these people Twitter was sort of better than Reddit, or so my sister says (she hasn't used Reddit, I haven't used Twitter).
