That’s not what a walled garden is. You can walk out at any time and keep everything you bought. There is nothing forcing you to stay there. Getting in is a bit harder than opening a web browser – but that’s getting in, not getting out. It doesn’t matter. It’s not like you have a right to buy something there.
No you can't just walk away. You need to authorise a machine to play DRM infected media from iTunes and you cannot play DRM infected media on devices which do not support FairPlay.
I am referring to music purchased pre-2009 (which is a large volume of sales), current movies, books, and television shows.
I don't have a right to purchase but the majority have a reasonable expectation to be able to take their purchases away in the future in the same manor as they expect their purchased DVDs to be usable on every DVD vendor's equipment.
This is getting more idiotic every time. Are you for real?
First, I was explicitly talking about music. Second, DRM is no more. That’s it. The music store was a walled garden. It is no more. To call it a walled garden is stupid.
