99% of people don't read anything before they push yes. Most people get increasingly annoyed at the mountain of e-mails, and the hundreds of pages they in principle has to read through.
No offense, but this feels like a “99%” and “most” that is something less than rigorous. I don’t think sound arguments for or against GDPR can come from the “Ah Reckon” space. Throwing out made-up numbers that just represent personal assumptions and anecdote is an impediment to real discussion of these issues.
I’d add that GDPR explicitly forbids just the kind of “press yes to forfeit all of your rights” crap we’ve seen before. I realize that some sites are still trying to get away with it, it it’s non-compliant.
