Some variant on "reject" takes more effort like 70% of the time. Which is on purpose, of course. The ones that aren't maliciously-complying have a "necessary only" button that insta-closes it, but tons pretend that you might want to allow some spying but not all of it and make you go through another screen if you don't just "accept all".

Then it'd be possible to default it to "nope" (Firefox, and perhaps Safari, might do this) or to allow a "never, anywhere" setting the first time the question is asked, and malware and spyware vendors know that'd mean a much larger proportion of denials.
But of course, designing the system that pushes people to make this sort of decision was absolutely intentional.
So even when it's incompetence, it's still malicious, just in a way that obscures the explicit decision-making that led to the result.
