This shouldn't be surprising. Ad placement is based on who pays to be placed in front of certain audiences. It doesn't matter if you're really into hi-fi amplifiers if no hi-fi company placed ads for that audience segment or if the hi-fi companies were outspent by boner pill salesmen.

Google is not optimizing for relevance but for revenue.

All the more reason for me to block ads. If relevance were the optimizing metric, I might see ads for things I'm truly interested in, but if YouTube is only showing me the highest paying ads and it doesn't care how relevant those ads are to me, they are just noise I need to ignore or block.

Especially when they are mostly scams and trash paying to be in front of my eyeballs. I have no desire or obligation to be propagandized, tricked, or misled by bad ads just so I can watch a video I actually am interested in.
