Let the free market run its course and let pirate sites compete with streaming services to improve their services.
The only way they can loose that race is tying themselves to an anvil and taking a shotgun to both kneecaps, and it would still be close.
Non Sanctified streaming sites can't load balance automatically, customers have to manually switch between different video sources. 4K isn't even an option. So many many ads. And adblockers on mobile aren't as good. Downloading for offline viewing is a joke. Captions sometimes completely broken, and only a few languages. What's audio description?
Netflix so freaked out that people will just download a copy of the whole thing. But it's happening already, and most people cannot afford to have 4k copies of the office filling up their only harddrive. Datahoarders are a tiny tiny minority.
