I figured, but maintaining that is such a waste of human life and parsing the list is a waste of my CPU time. Since no one on either side of the fence wants the notices to exist, web developers could just use a de facto standard element class and ad blockers can add a simple rule.
Is it a waste of human life? From a utilitarian perspective, it’s easy to see how one dev coding for an hour could save cumulatively many hours otherwise wasted by users clicking through GDPR/cookie pop-ups. From a purely “time invested” vs. “time saved” perspective, maintaining Adblock lists is likely a net benefit.
Ad/tracker block lists, yes, totally worth the effort because we have to fight against people that want to use our own machines against us. For the cookie notice, we're all on the same side, so we can make it easier for everyone.
