Earlier quoted context omitted.
> You think these websites give a shit about your privacy because you clicked on a div with a "No" in it Yes. For a subset of "these websites". Because this is enforced and EU has fined billions already. The fines for doing what you say they do, are steep and a severe risk for many "these websites".
> For a subset of "these websites". So for websites that are not in that subset, they will still track you regardless of what you click on, so you still need browser-level protections for those websites, and those browser-level protections will also work on the websites that are in that subset, so you still gain nothing by clicking the No.
Edit: what I'm trying to say is: this "technical" problem has a real and working "solution" that's not technical at all: law and enforcement. Now, that won't work for all and everything, it never does. There will always be malicious, scammy, malware, criminal and illegal webservices around. But it makes it very hard for malicious actors to do so and make money.
