As may have pointed out, GDPR does not focus on cookies per se, but Amazon (previously) and Google has put tracking cookies even while declining them. The point is Google is not putting only the "I have opt out" cookie, but putting instead "I have opt out and my ID is 751DBC849846494494A894984" cookie (which is the issue at hand). Edit: this should be opt-in really, as tracking is explicitly stated as a consensual activity.
