I have never seen a helpful ad in google search

That's a good thing.

I don't mind ads, as I understand that without money, web sites go away. But I'm very careful about being tracked. That, I don't think is cool.

It's not unusual for me to see ads for companies hundreds or even thousands of miles away, and often selling things for which I do not possess the correct body parts.

I consider that affirmation that I am mostly successful at staying off the ad-tech radar.

I mind ads and don’t think sites would go away. They’d just be less profitable.

I mind ads because they crowd out less profitable margins and result in worse products. Imagine how nice and useful Google could be if they optimized for search instead of ads.
