Earlier quoted context omitted.
I've yet to find any rights and protections in these cookie banners.
The cookie banners are corps trying to circumvent the rights and protections. If they actually went by the spirit of the protections, the cookie banners wouldn't be needed. Your ire is misdirected.
The ePrivacy Directive requires a (GDPR-level) consent for just placing the cookie, unless it's strictly necessary for the provision of the “service”. The way EU regulators interpret this, even web analytics falls outside the necessity exception and therefore requires consent.
So as long as the user doesn't and/or is not able to automatically signal consent (or non-consent) eg via general browser-level settings, how can you obtain it without trying to get it from the user on a per-site basis somehow? (And no, DNT doesn't help since it's an opt-out, not an opt-in mechanism.)
