Spotify, Google, Amazon, Apple, Tidal all manage to have almost comprehensive music catalogs for me to stream. It's rare that I find something on one platform that isn't on another (Some artist exceptions exist, and are rare).
Pick 10 random films off the AFI top 100 list and tell me how to stream them. How many services do I need to watch them "for free".
Consumers want a single point of access to content. If I want to listen to a song I go to my music platform, if I want to watch content I go to the web to find out who has it... That friction is what consumers dont want or need.
