Twitter started more aggressively enforcing the rule after the rollout of paid verification.
There are plenty of people on twitter who make fun of and/or disagree with Musk... including the engineers that publically disagree(d) with him
But it isnt, I would say, conspiratorial or personal, its just galvanized fan boys reporting accounts. And I assume with the diminished staff they are just airing on the side of banning then going through thorough reviews or whatever. Which is still pretty bad.
