It could be that there was so many different ways to listen to music: PC, iPod, non-iPod MP3 player, car stereo, burnt to CD. The DRM on music felt crippling.

It could be that there was so many different ways to listen to music: PC, iPod, non-iPod MP3 player, car stereo, burnt to CD. The DRM on music felt crippling. There is not as many ways that people watch movies, though. Still, if this type of revocation becomes a lot more common (the movie studios wouldn't do this for just one movie ever) then the same might eventually happen with movies. Once people feel crippled enough by the DRM, there will be push-back.
