Actually, the best way to fight this would be to fund people to break the DRM blob. What better way to drive home the uselessness of DRM than to have zillions of people having an automatic plugin that bypasses DRM everywhere it runs?
The ad-blocking plugins are so successful because their so easy to get. If something's illegal to distribute, then it's sufficiently inconvenient to obtain (tormenting, etc.) that most people won't bother.
