The funny thing is using a good adblocker and I haven't noticed a single youtube ad, so if they're to blame, they're also the solution. I don't see how this move functionally does anything other than punish those who can't block ads.
People that know what ad blockers are frequently use them. The act of punishing the group that isn't aware of adblockers simply will drive more users to discover/make use of them.
“We have to punish you because of what those other people are doing to legitimately evade punishment” is only a useful argument if the punished group can somehow cover for those not affected.
The only reason adblockers would be to blame would be because Google wanted to make up for lost revenue, similar to the myth of high end department stores having high prices because they expect their customers to shoplift.
