I disagree with this. Pirating makes the problem apparent to the MPAA; people want their products, but the existing distribution channels are not working. If people didn't pirate the MPAA's products, then the MPAA would conclude that nobody wanted their products anymore. That wouldn't result in positive change for people that like movies but want to play them under Linux, for example.

Piracy proves that DRM only hurts the people willing to pay money for the product. It has no effect on piracy whatsoever. In fact, DRM may be causing piracy.
