Today I filed a formal complaint against #YouTube with the Irish Data Protection Commissioner for their illegal deployment of #adblock detection technologies.
Under Article 5(3) of 2002/58/EC YouTube are legally obligated to obtain consent before storing or accessing information already stored on an end user's terminal equipment unless it is strictly necessary for the provisions of the requested service.
In 2016 the EU Commission confirmed in writing that adblock detection requires consent.
I would recommend people read the IAB ad blocker detection guide for Europe which provides a good summary of what is possible. It lays out the that depending on how the detection is done it might be defensible to rely on ToS, and to remove all risk, implement a consent banner, wall, or both.
Which is to say, even if it was ruled that YouTube can't rely on ToS, which I don't think is a sure thing, they would just have a consent wall like for cookies.
