EDIT: I didn’t realize the anger this would bring out of people. It was supposed to be a funny meme based on recent real-life situations I’ve encountered, not an attack on the EU.
I appreciate the effort of the EU cookie laws. The practice of them just doesn’t live up to the theory of the law. Shady companies are always going to find a way to be shady.
How does that work though? The cookies are presumably based on things like your IP and browser metrics, which a site gets from your browser. If your browser throws away the cookies then on your next visit you aren’t volunteering that you’ve been there before. But the site can still likely figure it out, but without the cookies it isn’t as certain. With well-constructed cookies they can be almost 100% sure you’re the same visitor.
Cookie consent is actually supposed to be about all data tracking.
There are quite a few analytics that do fingerprinting “because it’s not a cookie, it’s not covered by Cookie Consent”. But it is still covered.
Some of them respect the fact that declining cookies is about declining tracking.
So, if you consent to all cookies, you are also consenting to any fingerprinting that doesn’t rely on cookies. So deleting cookies wouldn’t remove that fingerprinting data.
Gotcha, responsible site owners should not be tracking you if you decline cookies.
