I agree with everything you said. I think you meant to write this to the other person. They kept trying to blame the entirety of leadership for a leadership failure and suggests “picking better leaders”.

I, like you, suggested that the process needs to be improved but I’m not sure how.

And how can what they did – presenting their own decision to other organisations or levels of their own organisation as if it were the legitimate “Leadership” consensus decision – how could that be anything other than a conscious and intentional act on their part, i.e, to use your term, “sabotage”? It's not like it could somehow be an accident, is it? “Oops, I slipped and fell onto my keyboard and these somewhat coherent and grammatically correct e-mails went out”?

Of-fucking-course it was sabotage, and of course they should be fired as all hell.
