It's a bit of a mess really. Musk fired the deputy general counsel the other day, commenting shortly afterward that he had only learned about the man's previous stint in a similar role at the FBI on Sunday. People quickly pointed out that Musk had actually commented on the tweets about that person and his FBI connections last April.
I feel that what we're seeing is largely investigation theater designed to validate a particular outcome rather than a real inquiry. If you consider this from an information/hybrid warfare point of view and think of Twitter as territory, then it's reminiscent of highly engineered plebiscites that precede or follow invasions to give them an aura of legitimacy.
