Why so surprised? It's beyond the concept of modern management to accept responsibility for anything negative. Blame is the name of the game, as well it might be as refusal to accept responsibility is generally rewarded.
The idea that management are remunerated to take responsibility is alien to most. It used to be that that was their job. No longer. The buck used to stop at the top, now it is passed ever lower down the chain. This ability requires bull**** and political skills, not management skills. Thus explaining why the general level of genuine managerial talent is so abyssmally low.
