It's key that the MPAA is a non-profit. Instead they are fear-mongers, occupying the buffer between DC and Hollywood. They convince Hollywood that it needs copy protection, then extort a price to deliver that. They convince Congress that it needs ratings, then use their collective power to deliver those. This is a natural role for Valenti, who was there at the Gulf of Tonkin, urging LBJ to shoot into the fog.
Ratings is really their stock in trade and where they have the most power to shape the world.
It alway bothers me to start pissing about Hollywood because there is so much talent and creativity there in spite of the lousy business elements. Proxy-writing laws which nullify Supreme Court decisions and erase rights given to citizens is just another offense. It's really an organization who's time is over.
