I think what would work best in an ideal scenario would be a free and independent platform. Something like Wikipedia or something.

Part of the subscription would be to keep the platform itself up and running, and anyone like Netflix, Disney, Fox, whomever would be able to upload their movies/shows/etc there, with no discrimination.

Payment could be the platform maintenance fee + access to the library of shows (and here more popular creators could get a bigger share of the pie) or it could be maintenace fee + paying for shows individually.
