"I'm going to stick with 'cause they are all greedy a-holes who use possible sales as merely permission to be data fetishists."
It's so broken that, for example, staying at a hotel in Central France because the road was blocked with snow ahead sees me deluged with adverts to return to the same hotel. It's not going to happen guys, it was a distress purchase. I buy, say a DIY item like a drill, I get besieged with advertising for drills. I'm not a site manager, one drill should last me the rest of my life.
It doesn't even work for things I buy often. I'm working on a project where I need several mini PCs. I buy a handful from suppliers to test, I find one I like. I'm now receiving adverts from every single manufacturer tested for their mini PCs. But, the type I want is no longer in stock. So I'm getting ads for stuff I would never buy. So what happens? Yes, I add the names of the advertisers to my list of "Organisations that I will never do business with." Way to go, guys.
