If you're neither paying YouTube any money nor watching their ads, meaning you're a pure money sink, why should they care about your goodwill?
This may be making some metric (account signups, presumably?) go up, but sure seems risky to me.
On YT, the people providing the value are the content creators. That is the same content creators who get a revenue share from ads and premium. They're the ones who benefit the most from blocking ad blockers. The people watching videos with ad blockers (and sponsor block)? They're not providing anything in exchange, to the platform or the creators.
b) YT is a propaganda engine, too. It serves that end to allow nearly-unlimited membership.
