This is arguable. HTML5 EME can be used to mix ads into video in realtime. EME must run in isolation, so even browser vendor can't implement neither active blocking, nor ad detection. Still banners also can be implemented as video elements.
- Mathnerd314 9y agoDRM is basically in the same boat as ads, the user / operating system has all the power. The code is running in a sandbox; it can do integrity/sanity checks of the sandbox, but if the emulation is good it can't look outside the sandbox to discourage "bad behavior" like blocking ads or recording the stream for later.

But Netflix's content, which people do care about, is being shared on torrent sites. DRM is effectively useless.
