I never understood it (third party cookies getting external information) either. Same thing with the referer request header, or user agents, or disabling the right-click menu, or editing the browser history, or opening new windows, or changing scroll behavior, or replacing the cursor icon, or autoplaying videos. There are reasons to want to do these things. In some cases it's difficult for the browser to prevent them. But I'd sure like it if the standards and browsers were on my side, not the side of those nefarious web developers.
