I agree with you. It kind of itches me that he was just so ignorant of already established knowledge. But then, this is exactly the point where we fall blind to alternative solutions because we are limited by our prior established rules. So I didn't want to judge, but yes he seemed to be very ignorant.

I would respect it for some team doing something as risky, that's what I wanted to express. That he took paying customers was unethical imo.
