You reject the notion that people making up a corporation can control it but then expect people from outside it to be able to do that?

At the very leaset everyone inside the coporation can choose to quit. Yes that may not be an easy choice but that doesn't mean there isn't a choice. More often than not the choice is not nearly as costly as people want to pretend. And yes we should hold individuals accountable for making immoral choices just like "I was just following orders" should never be a valid excuse.
