Subscription based service makes data harvesting much easier. Spotify can force you to connect to their server even if you downloaded your song, in the name of “verifying your subscription”.
Buy the songs, buy the movie, take them offline.
That being said there are good subscription based service, like home assistant cloud, where all your communications are always E2E encrypted and cannot be seen by their server. Their subscription model is justified, as they rent their servers.
