The entire European Government already has done that several times.
Strangest thing happened yesterday evening at my Xbox 360. When i opened up the new Zune video channel to watch some of my downloaded trailers i was surprised to see a new agreement contract (updated december 16 2009) i had to agree upon.
I started to read that agreement and it's an amazingly LONG and tedious read. I can not help but think that absolutely nobody on this planet has any idea what they agree upon. I wonder if that isn't forbidden by local laws here. I do remember that contracts or agreement have to be in plain understandable local language otherwise you can get out of it.
Back on topic: Its a shame they use their own wicked license agreement to keep 3rd party hardware developers out of the loop, but i doubt anything will happen. Perhaps all the people who bought such a device should participate in a class action suit or something?
