>based on the ads everyone get

I'm not sure what you mean here? In context I suspect you mean 'because ads were chosen from a perspective of knowledge about you'?? But that's really opposite my experience (UK).

Ads now go hard on brainwashing. Same advert over-and-over, almost never anything I want to buy.

YouTube suggestions are pretty much inline with my previous viewing though.

My ISP has a list of every domain I connect to, my streaming providers know every video we watch, the supermarkets and credits companies know every item we buy at the shops, but still the brainwashing attempts continue for things we'd simply never buy.
