Don't buy that this is undetectable - browser sends a lot of signals, including position of the mouse and interactions with content, so it's not a big stretch to say that it would be possible to detect interactions or lack thereof in the area that is supposed to be the ad and determine that it's likely blocked. Once detected, publishers are free to not let you consume content via paywalls or simply letting site break. It's also not going to be able to be effective against stitched video, especially if the player playlist doesn't let you skip around easily - at best you'd end up with blank screen for the duration of the ad. Sound is another problem. We need better solutions for advertising, not yet another escalation in blocking that will lead to even more intrusive/annoying behaviors. (Much louder sound from stitched mid-rolls than the content anyone?)
