Cookie banners is not a policy, it is used to work around a policy, and often implemented incorrectly. GPDR says you need to be given a specific informed decision, but often cookie banners show a big green approve button, and a less positive deny button (if that is even the case). When the law is being enforced better (Which is slowly happening) those cookie banners should get 2 the same looking buttons, and that would result in more denies. Hopefully, companies would realize that they need to solve their marketing differently.
