Why do people hate DRM so much? The originators of the material have a RIGHT to control how their content is distributed. The only genuine reason to complain is because it makes it harder to steal content, hardly a valid reason to be angry. Instead of complaining, people ought to work closer to ensure DRM is available on all platforms as currently most Linux distros don't ship anything for accessing this material legally.
That being said, I don't think DRM should require any license in and of itself. It should only be used to ensure people have paid fair price for other material. That way, open source projects could still empower their users to not be left behind in content.
