I would love an option that allows me to set defaults for all websites that I visit. Such as to reject marketing and tracking cookies and other mechanisms used for that purpose globally and to allow me to fine tune functional stuff on a per-site basis.
Lol. The consent popup on this site is nearly identical to the "dark pattern" example in the Cloudflare Zaraz blog post. No reject all option. You have to click learn more to customize to deny cookies.
I use Consent-O-Matic. You can configure how it should behave. By default it'll reject things. For the websites it doesn't support I often use reader mode.
Cookie consent banners as we know them were constructed by the IAB as a framework made of dark patterns to annoy people into allowing adtech cookies. The idea was to be as annoying as they could get away with, so that end users would blame the GDPR. https://www.vice.com/en/article/m7epda/its-bad-design-on-pur...
It's quite good! When it doesn't work, there's a 50% chance (or more) that the banner doesn't allow you to reject the cookies without payment, which somehow is actually legal.
