Maybe. It's not been a very prominent line of business for them, and even then I can recall a couple of significant dramas over that time - didn't they merge two different kinds of libraries and cause confusion? The unremovable U2 album is also a cause for concern, not because an extra album is bad but because it implies they see the contents of your library as up to them rather than you. Most of all, they went out of their way to break music being sold by Real for iPods, which hardly suggests a company committed to interoperability and open platforms.

> Hell, they ditched DRM on music in that time period too and will sell you lossless ALAC as well as MP4 audio. (They obviously weren't able to talk Hollywood into that.) Steam is DRM that ensures the capability to pull rugs.

Not "obvious" at all, and precisely the point at issue. I'm happy to buy music from Apple, but movies require another level of trust that they haven't reached yet. I will grudgingly, cautiously buy games from Steam when they're not available on itch/GoG, and maybe that's unfair, but Apple have never sent me the message that they want or care about me (a non-Apple hardware user) as a customer of their movies.
