It wasn't an argument. It was a messenger bringing bad news they didn't want to hear. And with other messengers who were actively telling him untruths about reality. And he wasn't sufficiently technical to go evaluate the claims himself; he -had- to decide who to listen to. So, unsurprisingly, he listened to the one that felt better. You seem to believe that everyone is mature enough to hear bad news, delivered objectively, and accept it without blaming the messenger, and without dismissing it because it doesn't conform to their wishes. I wish I had your luck in bosses.
