As I understand it, detecting an adblocker is a form of fingerprinting. Fingerprinting like this is a privacy violation unless there is first a consent process.

The outcome of this will be that consent for the detecting will be added to the TOS or as a modal and failing to consent will give up access to the service. It won't change Youtube's behavior, I don't think. But it could result in users being able to opt out of the anti-adblock... just that it also might be opting out of all of YouTube when they do it.

I'm happy to report that the vote was postponed because they did not have the votes for the proposal to pass. I know it is not a definitive victory because they will simply try to do it again, but it's good that they failed once again.
