I think what would save the streaming industry would be anti-exclusionary legislation. Prevent contracts where shows are exclusively produced for one streaming company. Then streaming platforms compete on cost, curation, and interface, not on exclusive content.
I mean, shit on the music industry for all of their crappy practices, but 100% this. I pay for one music streaming service and have access to any music I want without having to think about which record label released which album. Why is it still illegal for studios to own movie theaters, but not streaming platforms?
Decouple the content creators from the content distributors.
