I don't know how true this is (it could just be rumours) but I've heard multiple times from hardware vendors that the main reason they can't open source GPU drivers and firmware, or the code for a smart TV, is because of concerns about the DRM being cracked. It would be a pretty sad state of affairs if the end result of this copyright enforcement is that the general public just isn't allowed to know how a TV or a GPU works anymore, and that right becomes reserved only for the 5 big movie studios.
