I saw a certain producer abuse engineers. It was disturbing. Hissy fits and anger management. All entitlement, all the time. The minimum wage engineers would lose jobs if they responded how one should to an asshole.
It that was long ago, absolutely nothing to do with these old links from musicians describing a rip off.
