I don't agree with the way you're interpreting the comment. If anything I think it's BAD that you don't really "own" digital content.

I guess my argument is that Amazon shouldn't be able to have their cake and eat it too

You agree that we should own our digital content but it sounds like you don’t want this particular capability because… fuck Amazon.

I can totally understand that sentiment but I don’t think giving up end user capabilities to spite Amazon is logically aligned with wanting ownership of digital media.
