Let's say facebook runs an ad on its platform to my website with a url of site.com/fbad. Then I can see how many people clicked on the ad on facebook and how many people converted on that webpage. There are people on this site who will tell you, and FULLY believe that that is TOO much tracking and is morally wrong.
Come on, don’t be obtuse. The problem is not advertising, the problem is tracking and using user data without consent. The fact that they do that for advertising is irrelevant. They would have the same issue if they were doing it for any other reason.

That’s what they did. It’s called the GDPR. One can argue that enforcement was insufficient, but the standard has not changed.
