Earlier quoted context omitted.
I don't think that's actually true. Rather, it's an architectural thing — because all these ad systems were designed without consent in mind, accepting is a no-op, whereas refusing consent requires an outbound request to set some sort of "do not track" flag somewhere (presumably as a cookie).
If accepting is a no-op then you are being tracked even before you make your decision - as the page already have been loaded. A brutal violation of course but I absolutely expect that to be the case.
I’m not holding my breath.
