Apple may always come off as the good guy, but privacy advocates have discovered that iTunes songs can include information about the buyer, including name, e-mail address and more.
The theory is that this information can be used to hunt down the folks that offer up these tunes on file sharing networks.
So Apple acts all nice by demanding that publishers take DRM off music, but in the meantime, it uses a secret way of tracking down people that copy it? It is a catch 22 either way.
