This whole thing is dumb. Facebook, YouTube, etc. should have very detailed lists of what categories of ads are available. Then we can choose what ads we want to see. No need for all this spying around.
YouTube is particularly silly. I’m interested in trucks, and in DIY home repair. I get ads about body wash and shooting games. I suppose YouTube uses some kind of algorithm. But it’s a darn bad one. And their page to customize ads is pretty poor, too.
Maybe they want to sell how you react to those stupid ads. The more clicks from you, the better.
