In my case I was kinda OK with Google ads until around 2010 and IIRC only began blocking them actively after they had been feeding me trash ads for years.

Maybe you are right in most cases and I was the victim of a fluke.

But from what I have seen from Google after that I don't think so.

Facebook however, a company I disliked then and dislike now are scary good with their ads and have often been even even when I actively tried to avoid them.

All this to say that your theory sounds interesting but I am convinced it is far from the whole story.
