The biggest takeaway from this is the dark patterns sites aggressively use to trick you into accepting all their cookies, by making use of creative language that might take a while to parse for the impatient reader or setting buttons to common colours that might confuse someone into clicking.
I really wish there was just a setting in the browser that just says
- Accept 'functional/mandatory' cookies (with exclusion support for sites that abuse this...)
- Reject advertising cookies
- Reject personalisation cookies
- Reject analytics cookies
- Reject tracking cookies
etc. and this config is available for these GDPR banners to query and apply the appropriate settings.
