I was prompted to consent to some stuff, which I unchecked. Then there was a "vendor preferences" button, where they were basically saying "ok, even if you don't consent, maybe you still wanna give them access if they have a legitimate interest". So since I have also a legitimate interest in not giving my data to shady fucking companies, I spent the next 10 minutes removing ticks from boxes basically, because fuck giving me a choice to "uncheck all", that would make it too easy to opt out.

Edit: and then to make it even more fun, I found a button somewhere in settings where I could remove my consent for gdpr-related reasons. So I clicked it. You wanna guess what it did? If you're guessing it removed my consent, sorry - it actually removed my "lack of consent" - that is to say, it reset the settings and prompted me to uncheck everything again. Cool beans.
