This post came out just after the board posted the original notice, but before the reasons for the removal became public. So it seems like it has too much factual detail, unknown at the time to outsiders, to be entirely fake.

It would be very easy to identify them with what they wrote if what they're saying is true (even saying they were "in the room while this all went down.").

I think it's real, but they're not as senior as they seem. Or alternatively they've taken a serious, stupid, risk as senior leadership which calls their judgement into question.
