The funny thing about legislation is that you're responsible for the unintended consequences of your laws too.
Let's say you make a law to reduce working hours from 40 to 37 hours except in "emergency situations". Now a company will force employees to sign off on "emergency situations" every week or they'll be fired. They're clearly not complying to the spirit of the law? Is it really your fault when you make a law like that? I'd say only to some degree, the people trying to abuse every loop hole are much more responsible in this case.
Companies using dark patterns, hiding the "reject all" option behind an additional click (which even is illegal) and even trying to collect all data possible are much more responsible than the EU's law. Oftentimes they are collecting data just because, not even thinking about it, because they'll add GA to their WordPress site without even looking at it or whatever. That cookie banners have become the standard around the web is sad because it just shows how much everyone is trying to track you.
