My website has no tracker nor any third party cookies so it doesn't need cookie dialog. And even if I had some analytics that stays on prem, doesn't store or gather PII, I wouldn't need one.
The first dark pattern, is that websites want to send all your PII and other data to other companies, and act as if this is normal.
The second dark pattern is how they do this. They could just not track and share this data, but allow you to flip some setting if you really want them to gather and sell or share this data. No popup needed. Or one that has some big button "proceed" that denies all tracking and a tiny link "advanced settings" that allows opt in to tracking. Instead, their UX is the exact opposite. Sometimes with deliberate javascript to make the "nope" button not work, slow or clumsy.
