My definition of Evil includes coercion. Apple doesn't coerce you into using iTunes. They market an iPod to you, which you buy voluntarily. It's only after that you have to use iTunes. And even then, you don't really have to, since there are alternatives for software.

If you can opt-out and just not pay for it, then it isn't evil. It still might be "shitty practice" but you can still vote with your feet.
