Bagging on Hausmann reminds me of people who made Captain Lord, the captain of the Californian responsible for the Titanic disaster. The wireless operator on Californian who was communicating with Titanic was told to "shut up", so he turned off his radio and went to bed shortly before Titanic hit the iceberg. The White Star line and British Trade Board deflected all the things that led to the sinking, like steaming way too fast at night through ice, and the drownings, like too few life boats, to somehow be Captain Lord's problem.
Same philosophy here. Frost and his staff turned out to be totally dysfunctional and when a guy gets sick of the clown show and moves on, it is somehow his fault for being disloyal.
