Cookies are not inherently bad. How do you think identity and access management (logging into websites, etc) work?
I don’t think you understand what a dark pattern is.
Isn’t it when ui/ux uses deceptive practices to confuse the user into doing something?
Yes. It’s when the UI leads YOU to do the thing you don’t want. So unless the banner telling you that the site uses cookies is doing something to make you accept them when you don’t want to accept them (such as by not having a button to not accept them visible) having cookies itself isn’t a dark pattern.
Blame the EU. There, cookies used to bother a tiny number of “privacy advocates” who were already perfectly capable of blocking the cookies in their own browsers but they weren’t happy because no one else cared about cookies so they got the GDPR passed to bother everyone in the world.
Not the EU’s fault that all those websites want to invade your privacy.
The EU only demanded consent. That all those websites care more about marketing than about their users says more about those websites than it does the law.
