"Buying" digital files from Apple/Amazon whoever is where I feel like the least value is.
At least for music they've mostly gotten rid of the DRM, so they lose the ability to take your music back.
But at this point buying digital files saves nothing over CD. I feel like you either need to just stick with streaming or if you must purchase buy CD/Vinyl as it's pretty easy to argue it's a better product other than the case of wearing a vinyl record out, which is awfully rare.
My biggest exposure to digital ownership is books, followed by games. I am very very unlikely to care about re-playing games. Books I'm a little more likely to re-read. But paper books take up a lot of space and I'm more likely to have to get rid of them before I get to re-read them.
TV/Movies I just don't care, I watch it once and that's enough, so it's rare I would ever buy them. And even if I have to buy them it's less than going to the theater once.
Now if I go to a digital store, select a specific movie or show or song, click « buy » or « purchase » and pay full price (sometimes more!), I have an expectation to own the media indefinitely. Not « as long as the store is licensed to distribute it ».
These stores simply shouldn’t be allowed to use words like « buy », because it’s a blatant lie. Prime Video is pretty clear that you can rent movies at a small price. That’s clear, there’s no expectation of ownership either.
Buying without a discount only to then lose access is different.
Spotify's artist compensation is laughable, though, so whatever good stuff I find, more often than not I seek out physical media. (Much to my wife's despair...)
