Well, saying things like "I can tell you that all the good people who could’ve left haven’t yet, and that all the people who should’ve resigned, haven’t yet." does feel like there are fingers being pointed, but of course it's not clear who they are being pointed at. But I guess the people involved at least know who they are referring to, so at least that's good.
But let it be noted that "should've" != "bad/malicious" (at least, that would be my reading). Rather I think it's more about bad fit and incompetence in a specific responsibility.
