I too find it quite annoying. The other issue is that sometimes the banners do not properly work with various aids for disability and keyboard-operated browsers.
There is the "Do not track" option, but as I understand it's ignored by most websites. That's why I wouldn't mind a "Do what ever you want" option, and in exchange popups are removed.
That's how it was before and I'm not certain that it caused that much harm. Users can always block ads and third-party cookies anyway if they wish to do so.
