See the big difference between TV and music streaming. I can switch from Spotify to Apple Music without losing access to most of my songs, but Amazon can't show 'Netflix original' series. I get that movie studio's don't want to 'flat rate' their premium content. Online movie "purchases" seem to be better covered. You can buy/rent about the same movies from Apple, Amazon and some others but they cover a very small number of popular movies. Older movies like the Criterion collection needs yet another subscription which isn't even available in big parts of the world, especially in the EU there seems to be a copyright clusterf*ck of epic proportions where every member state has it's own rule, regulations and small time film licensing companies making it totally impossible to release niche content. Combined with the demise of disc-based movies (I give it about 10 years before major movies are only streamable) I fully expect an increase in enthusiasts resorting to piracy. It really is a service problem...
