However it's deeper since the popups we see today were never recommended nor required by the original regs. The laborious nonsense we endure was invented by websites as a workaround for the regs. So it wasn't obvious that consent parity would ever need to be clarified like this because it wasn't even obvious that the industry would come up with such an awful popup pattern to begin with (though in retrospect we should've known I guess).
The fact the popups were never even compliant anyway is just a combination of wilful ignorance, dark patterns, consulting companies wanting to sell something and - yes - an added set of people innocently misinterpreting regulation.
