It's easy to see that websites want people to accept all unnecessary cookies, but are mandated to ask for it. So they'll give one big "Accept everything" button and bury the rest under as many clicks as possible. This is not an issue with the law, nor is it an issue with the users; you know how to make a better UX ? Remove all tracking content. You know how to make it as good as the way the websites owner want ? Make the "Reject all" button front and center.

The UX being bad is a _conscious decision_ by the website owners
