Because that’s how it is. For instance why does a site need to share my data with over 1000 "partners“?

And the EU uses the same tracking and website frameworks as others so they got banners automatically.

It wasn’t a mistake but website providers maliciously complied with the banners to shift the blame.

Seems you fell for it.
