Apple (and the RIAA) have a very draconian attitude towards ownership. Both seem to believe you didn't actually purchase anything tangible from them, just the right to use said product. Apple has tried to sue many people of modifying or jailbreaking their phones and MP3 players. Apple sales you not the song but the license to listen to one copy of that song, and only have it on one device at any given time - or at least that's how they view it. The RIAA (Recording Industry Association of America) seems to feel if you buy a CD you have actually bought the right to listen those songs from that CD only. You don't have the right in their opinion to rip it your computer, or create a digital copy on an MP3 player. You don't own anything physical, you own a license. On the flip side tho if you break the CD they wont replace the music, even tho they were just telling you that you only own the license to listen to that music. If the RIAA had their way they would make you buy a license for that song for every device you want to listen to it on.
I don't agree with Apple's or the RIAA's views on ownership.
I've never used an Apple product, but the idea of that doesn't actually bother me too much. They've probably only stated that to cover their own asses in some way, not to try and limit their customers. If I'm to pay for music, I'll physically buy the album. Although that doesn't happen terribly often. I feel better about just going to concerts and buying merchandise there to support artists, which is the only reason I would buy something (music, whatever) from a particular artist.
I think it's stupid they have done that.. Personally. But either way I only use iTunes too put music onto my iPod, buying music is stupid when you're able to find it for free on YouTube or where ever.
