IMO, one particular move of his that I think contradicts the claim that he “values the mission of X over financial considerations” is taking away legacy blue checks from notable people in favor of the Premium system. As a user, I preferred it when someone with a blue check was not just anyone that paid $8 or whatever the cost is now. But I understand that he wants to try to make money too.
Anecdotal, and I won’t get into the “more hate speech” allegation, but I’ve noticed more porn accounts replying in unrelated threads than pre-Musk. Oddly seems to be common under the replies of low-view tweets about college wrestling.
