I hear that too, and I mostly agree with doing it, but I kind of feel it's a problem: It tells amazon "Oh, sure, your system is fine, I don't mind paying for DRM!" when in reality we shouldn't encourage DRM.
I wish I could go to the studio/artist/creator directly and say "Hey, I would like to pirate your content, here's some money", but outside of Patreon or the like, there's usually not an option to do that.
I've no doubt if amazon could just sell the raw file they would. It's rights holders who demand DRM and if amazon refuses itunes or someone else will happily step in and provide it.
