I don't have any problems with the concept of DRM (controlling how a movie is used) but I have major issues with what is required to implement it. Essentially by definition you need to run some code that the user doesn't control on their computer. How Firefox does it isn't that bad because it is fairly well sandboxed but over time the urge will be to push it further up the stack so that gaining access to the content becomes more and more difficult.
I suspect give enough time they will push until they close the Analog Loophole.
It seems to me that the implementation issue is just a symptom of a deeper problem: copyright and DRM by definition grants a monopoly. This monopoly can be abused. For instance, if you want to watch movie X and it is distributed in such a way that you have to give private data, your options are not to watch it or get a "non official" version.
Could the copyright law be extend in order to prevent its abuse and protect the consumers, for instance by using the concept of "abusive clause" [0]?
