Imagine what could have been: a standardised prompt that is always the same, persists when clearing cookies, etc. Instead we have full screen modal popups that render 5 seconds after page load and move around while loading.
That could work, yes.
I can see why bureaucrats like this system though, try to inflict the horror of their jobs onto everyone else.
And ofc, this makes no difference for tracking at all. Most people just click whatever option is the default, they have no idea what cookies are, they have no idea how the cookies are being used because the forms don't tell you...what is the decision that is supposedly been improved here? People are still being tracked, but we showed them a totally baffling form and they clicked "Yes"...society has been preserved.
Oh, and you have now split the internet into different regions...it was all worth it, no ragrats.
