Then make some movies of your own and release them to the world DRM-free. That's the FOSS way. RMS couldn't find an OS he could trust so he started working on his own. Linus came along and tied it all together and now we've got Linux. The point is they didn't just bitch about things they didn't like on message boards, they solved a problem they were having and made the world a better and wealthier place for it.
The content that's getting DRM protection - that's other people's stuff. What they do with their stuff is their business. There's nothing wrong with them asking for web standards (that no-one's forcing you to use) to implement their protection. It's also their problem if they implement a DRM solution that prevents them from selling content to you. That's sales they'll never make and an audience they'll never reach.
I think DRM is self-defeating - content companies will prevent more sales than they'll gain - but there's a world of content out there that's never been protected by DRM. You could spend your whole life being entertained and enthralled by it and never once wonder what the fuck is going on on Game of Thrones or Piranha 4DDD. Or maybe you could add to that trove of free wealth for humanity. You know, contribute on your terms. Just sayin'...
