Earlier quoted context omitted.
Where are you located? I've never seen any of those. Pretty much all of my YouTube ads are for TV shows, movies, cars, mobile games, consumer products, and various consumer services. Volkswagen, Dove, TurboTax, etc. All incredibly mainstream. Maybe you're located in a country or region maintain advertisers avoid?
I'm in America. I only see these scummy ads I talk about, and I assume it's because I'm extremely aggressive about preventing myself from being tracked and profiled. My friends made the horrible mistake of looking into cryptocurrency on Google while signed into their account, so they got targeted by scum crypto ads.
I'm honestly not really sure why you're complaining. If you don't want to be tracked or profiled, you're going to get the lowest quality ads. Why do you think higher-quality advertisers should be wasting money trying to reach you, when you are going out of your way to avoid any interest in them?
To be clear, I'm not criticizing what you're doing to avoid tracking, or your stance against it. But I'm questioning why you would then complain about the ads you receive.
