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 have to read through.
It's an extension of the already existing kafkaesque "press yes to allow cookies" that everyday has to be pressed multiple times with no real benefits other than wasting peoples time (at least in the EU).
People are already completely over encumbered with information. The more people have to do the same thing the less they give-a-f.
This carpet bombing of legal jargon makes people hate services, especially the smaller ones i am sure. "oh i don't want to deal with lots of legal contracts again".
I completely agree that something has to be done about the data-mining and fingerprinting monster, but the way all of this is implemented only further exacerbates the mega-corp gardens because they can afford to hire armies of lawyers, and because people get tired of clicking "i consent" after the bare minimum has been done - which off course means only saying yes to companies highest on the Alexa ranking.
Ironically these global conglomorates are the worst offenders and the original data-disaster culprit.
