I literally watch TV through a capture card right now out of stubbornness and principle. Anything I want to record, I can just hit a button and safely keep. No DRM preventing me from taking screenshots, I can manipulate the picture to hide obnoxious graphics or ads (great for sports); the sense of control is extremely gratifying.

The fingerprinting I'm talking about gets encoded in the screen recording too. Subtle pixel changes here or there over the entire length of the video. It'll be lossy when it's transcoded, but over the whole video it's there enough times it won't matter. Even scaling to lower quality won't fix it and then it'll also be lower quality.

It'll be like DRM, there will be people trying to remove it like anything else. They'll break one thing and another will come along. There would still be a black market, but most people can get an unrestricted copy in exchange for money so there's one less reason to pirate.

Unless you're actually pointing a camera at the screen, then OK, you do you.

Like every system? What's the actual distinction you're trying to point out?
