nmk said:Most spyware makes you sign an agreement essentially allowing them to transfer your personal details to whomever they want. The fact that you signed this agreement doesn't change the fact that its crap.
But, in the case of spyware, perfectly legal (as far as I have heard). The principle is pretty simple -- if you agree to it, you should keep your word.
The agreement that you sign with Apple violates your fair use rights.
I am not a lawyer, but I seriously doubt that that is true in law. You can indeed make backups of your music. You can keep your music on a limited number of multiple machines, and, if that is too onerous, you can back up your music to MP3 as much as you want (sure, it's in a degraded form, but copying vinyl records and cassette tapes also introduced degradation, and I don't recall people complaining about fair use violations).
