Haha maybe that would reduce piracy.

The easiest way to watch a movie in the player of my choice - even if i have legal access to it because it's in my netflix subscription - is to download it off piratebay.

Add to that Netflix's shitty discovery system, I'm pretty sure I watched some downloaded movies in spite of actually having legal access to them.

Oh, remember when PC games used to come on disks? For the Netflix example I can only guess, but I'm 100% sure I downloaded isos for games I had actually bought and had the physical disc... somewhere.

i don't believe this is a significant driver of piracy tbh, normal people don't care about that kinda thing :P

especially considering most modern movie/tv piracy is free streaming websites - shitty quality and awkward player controls, definitely no choice of player here
