>Contextual ads wouldn’t require tracking as it’s just advertising based on the page context This sounds similar to the "you might also be interested in..." ads/recommendations you see on Amazon or Aliexpress. Those are actually pretty useful at times. If I'm looking at product X from brand A, and it shows me there's a competing product X from brand B, that's lower priced or a better product, that's useful. Or a product that works with the one I'm looking at. Of course, these aren't 3rd-party ads: these are just more products being advertised to you by the shopping site you're already browsing and looking for product X on, and not too different from going to a physical store and finding similar products placed next to each other.
