Maybe not innocent, but human. Many have spoken to his integrity, and given his apology (and the silence of the rest of the board), I'm inclined to believe he isn't so bad of a guy.
To me it just sounds like someone who was in a failed coup. Of course you'd apologize and try to stay in, specially if you're scared of progress of AI and you want to stop it from within. I don't see how he can remain there.
