No, but I know people wondering why this can't play this video in 4k or why their offline downloaded videos stopped working and they get a pop-up telling them that they need to go online to re-validate them.

Yes, not many people know what DRM is but many of the effects are noticed when it ruins their experience.

I agree, however they probably assume it's their fault or something to do with this arcane black box they use but don't quite understand how it works.

For me, I bought a single DRM book against my better judgement because it was the only available way to get it quickly at the time. Predictably, I eventually lost access to it and never bought another one since.
