Sony CD's install spyware?

[Gwarsbane]

but this is absolutely no excuse for compromising a system without any permission by the user

Well here is where there is another problem. On the CD there is a warning of DRM, it don't say what the DRM is though. And from my understanding when you open the packaging you are agreeing to put the DRM on your computer.

So people are agreeing to put the DRM on their system just by opening and playing the CD.
