He makes it sound as if he was unable to even know what he was being accused of in order to defend himself. He should be apart of that process even if it is in private.

Not being allowed to criticize something is the first red flag, for me personally, that the idea is likely to be worthless. There shouldn't be any debate about whether or not an idea can be criticized and the people in this thread who seem to be ok with firing/excluding a person because of their opinion... man that is just bizarro-land to me.
