So why do even the official website of the European commission and the European parliament have a cookie consent button? One would assume that they are not "capitalist services".
Edit: And as the sibling said, in many cases it may be restricted to analytics and simple 'reject' suffices, which is at least better than some of the intricate dialog designs.
"We use analytics cookies to offer you a better browsing experience. You have the choice to refuse or accept them. Reject. Accept".
Those analytic cookies are not required for the functioning of the website, and those web sites are required to ask for your consent to gather any additional data.
