The consent banners you complain about are not due to GDPR it is a different law plus a compliant website makes it as easy to reject cookies as it does to accept them.
I can feel that you are from EU. Just because the way you defend your arguments sounds so european. But, let me whisper it to your ears, this thing is shit bro. Literally, I'm spending hours looking at screen and this consent banner pops out almost every minute...I keep my right to take this to the court if I'm diagnosed with schizophrenia or whatever.
The popu repeating is definitely not due to EU legislation. You should only get it once and it shjould offer you the choice to accept all or reject all or optionally the complex choosing.
If it pops up every minute it is the website that is doing it wrong sue them.
