You're perfectly free to use an ad blocker as you always have. But for the people who don't block ads, it's obviously preferable to see ads relevant to them than totally arbitrary stuff.

google likely tracks you anyway through your search, youtube, browser history synced to your account, so yes, you take pennies from little competition google still have to actual google.

Exactly! Ad companies literally pay psychologists to convince people to buy stuff they don't need. Everyone loves to say "those tricks don't work on me!", but the reality is that they absolutely do. You see an ad for Coke a thousand times, and you're at the store and thirsty, hey, there's a refrigerator full of Coke and I haven't had one in a while...

I'm certain a company could convince me to buy a new mechanical keyboard or nice mouse or some app I don't need but that looks pretty cool. That kind of targeting might just separate me from my money. On the other hand, no one's ever going to convince me to buy any brand of tampons.

there are such browsers and search engines, but looks like majority prefers to use services with quality backed by revenue from relevant ads.

I think eventually Ads industry will catch up on those like you if it will threaten Ads revenue in significant volumes.

There were news already that they block people from playing youtube videos if they blocked ads.
