I do not believe for one second (I could be dead wrong of course!) that platforms know what I am spending money on. It is not that I am not getting perfect deals fed to me in ads, it is that I am getting fed things I do not have a slight interest in and would absolutely never purchase. I play tennis and if I was getting fed ads for racquets that cost $500 or tennis ball machines that cost $3k that would be one thing (not a very good deal and I would never spend that much money) but what I am getting are ads for hoola hoops which I would not buy even if someone was selling them for $1.
