I'm not sure what that's supposed to prove. There are only a few big studios, and they all happen to be wrapped up in inertia and paranoia. But that's just how the dice came out, it's not because DRM provides actual value. If they wanted to perform a realistic market assessment we could be DRM-free in a snap.

None, because currently it's not possible to get non-DRMed content from provider for various reasons - legal and dumb ones.

Does it need to be legal? $10/mo for usenet and it just gives you what you want, DRM free, often in better quality than other services offer too.

I used to be able to use Netflix alone fairly well, but the fracturing of online services is making me lean more and more on automated piracy tools like Sonarr. If I were going to pay $10/mo to a dozen services I'd go back to cable.
