iTunes didn't even allow you to add your own album art. To do so you had to be signed in with Apple ID, so Apple could look up the album details on the iTunes store and set the image that way.

This was in 2008, so the software ecosystem lock-in strategy was already well-established back then.

I was adding my own album art to ripped CDs since well before 2008.

This is utterly false: https://www.youtube.com/watch?v=bnBsIAiZfFc

You could always edit artwork in iTunes. Indeed, you could import albums from your own CDs and not even use the iTunes Music Store at all.
