Serving ads or doing tracking from random URLs doesn't work with extensions like uBlock Origin.

In Firefox, uBO can block first party domains: https://github.com/uBlockOrigin/uBlock-issues/issues/780

Also domain or URL blocking isn't the only thing you can do. You can also ban scripts from the page, or monkey patch JavaScript to change behavior that ad networks rely on. And you can also do cosmetic ads blocking, to hide elements from the page, via user stylesheets.

It's no wonder that Google is deprecating the APIs uBlock Origin relies on, in Manifest v3 ;-)

Fact of the matter is Google is now engaged in war against ad-blocking.

Again I don't get it. If a site wants to they can serve ads inline right now, without making client side requests to ad servers and ublock can't do anything about it. And first party cookies don't do any good for tracking so it doesn't matter if they come in the bundle. The ad trackers want to see where you go across multiple sites and there's no simple way to do that w/out 3rd party cookies (although you can use browser fingerprinting)
