With respect, knowing what went wrong (and clearly a lot did) will definitely inform the current board but if they're not already a long way beyond the point of learning lessons from it then all the fretting in the world won't change anything.
It's worth saying that accepting a bad situation isn't even in question, since you have no choice but to accept a bad situation when it already exists. The only question in town is what you do from here, how do you make it better. Also, all this biblical rending of garments by supporters doesn't count for shit anyway.
