One other thing I would note, incidentally, is that those calling for Hilmar to be canned seem to forget that one can't take a certain screw-up to be indicative of the capabilities of the man. Yes, he's made mistakes. On the other hand, he and others "at the top" have also done some fairly good work, including creating Eve, without which we would not be having this conversation.
Given that this is so - and letting knee-jerk criticisms of management profiting off the workers fall by there wayside where they belong - there is nonetheless the matter of this mistake costing workers their jobs. Shouldn't Hilmar and others, as the self-admitted responsible parties, share their fate?
Well, no. First, if you are the leader of any large organization, you will eventually make a mistake that hurts others in the organization. This is not just human fallibility at work, but also the human inability to predict the interactions of complex systems such as economies, player opinions, and competitors, among innumerable other factors which can dramatically change.
Second, provided that you have a person who can learn from their mistakes - and the fact that Hilmar has got this far seems to bear evidence to his being such a person - it is generally not wise to remove them after they have so learned. In removing them, you must by necessity replace them, and their replacement is likely to not have learned the same lessons. In addition to this, we should add in the fact that humans are not necessarily good at picking leaders or innovators.
This isn't exactly to defend Hilmar's mistakes. He has made mistakes, and, moreover, didn't realize them as soon as we might have hoped. Yet, I find myself irritated by the reflexive resort to vilifying "them", especially when I know that such vilification is often an overly simplistic portrayal of the situation.
Justice and fairness are certainly important. However, those virtues require us to understand the context in which decisions were made, the intentions involved, and the knowledge of those being criticized. Unreflective condemnation and calls for punishment are often counterproductive to true fairness.
