I imagine it wouldn't be Netflix enforcing that decision but rather the hollywood studios.
But why does Hollywood even care about this DRM in the first place? I don't really understand why all this wasted effort, going so far with HDCP encrypted video signals.. I mean every new release is pirated within hours despite all of these protections anyway, so what exactly is the point? It's even easier and faster to just download a 4K torrent than to get Netflix in 4k working on many system configurations because of these overbearing DRM requirements.
So ask the same question of them. Would you expect them to care about invasions of user privacy? To give up money over it?
