I don't give the slightest fuck about GDPR because of the dumbass cookie popups they forced on every single site.
Advertising is a hell of a drug.
I blame the GDPR for being drafted in a way that allowed this mess.
This "cure" is worse than the problem it tries to solve.
If the answer is "to target advertising" then what is the danger?
If the answer is something else, I'm all ears...
You only need consent if you include Google analytics or ads or a similar platform. Those platforms push the banners on people, pretending that those are needed.
The reason you see the banners everywhere is that a huge number of sites integrate these spy services.
