Cookie consent popovers were the deliberate decisions of company to create the worst possible compliance. A much simpler one could have been to stop tracking users especially when it is not their primary business.
Newer regulations also mandate that "reject all cookies" should be a one click action but surprisingly compliance is low. Once again, the enemy of the customer here is the company, not the eu regulation.
Perfect example of regulation shaping a market. And succeeding at only ill results.
I don’t believe that every website has colluded to give themselves a horrible user experience in some kind of mass protest against the GDPR. My guess is that companies are acting in their interests, which is exactly what I expect them to do and if the EU is not capable of figuring out what that will look like then it is a valid criticism of their ability to make regulations
