In all actuality it is the automotive industry buying up the movie studios and record labels. Since the content industry is doing so poorly, they are a bargain. They are doing this to preventing people from modifying, or doing tune ups on their cars.
The point is actually moot anyway. By the time these treaties are enacted, we will have the ability to 3D print any chemical imaginable, from a small stock of raw materials. Doing away with any chance any resulting pharma laws have any chance of succeeding.
Data sticks in 10-12 years will be in the quad (q-byte) range, making the distribution of all music and video from the past a simple thing. Bit torrent is implementing a distributed private network system that you need to be invited into. Add encryption on top of that and you have private interlinked darknets galore. All this leads to the obvious conclusion that any RIAA or MPAA based laws will be ineffectual and impossible to enforce.
All in all, it doesn't matter if they get one, or even all of these treaties enacted. Advances in technology will cause them to fail horribly.
