What we actually need is a ban on exclusivity. There aren't nearly as many complaints about music streaming services because most music is on all of them.
Plus if more TV and movies were on multiple streaming services, they'd have to start competing on service instead of exclusive content and maybe actually improve the experience...
Unless it's just taking a while to come down from the scene group heavens, some 4K TV show seasons seem to be perpetually missing, presumed due to Widevine L1. Oddly, sometimes half of a show's 4K seasons are released while the others aren't.
Streaming services did it the other way around. We had one platform for almost everything, and then the studios created their own to get more of the subscription money.
There are lots of streaming platforms, but no real competition. Because the studios and networks hide behind the streaming services and price gouge like crazy. They know people will blame the streaming service.
