Bad publicity for Sony’s DRM is busting out all over. First there was the post about Sony music CDs silently installing a rootkit when you insert them in your computer, and now we learn that Sony is using DRM to fight with Apple over opening the iPod. Of course the iPod works fine with unprotected audio files, Apple just doesn’t support competing DRM. I’m fine with that. (I don’t buy tracks from the iTunes Music Store.)
