EU ruling: tracking-based advertising by Google, Microsoft, Amazon, X, across Europe has no legal basis

EU data protection authorities find that the consent popups that plagued Europeans for years are illegal. All data collected through them must be deleted. This decision impacts Google’s, Amazon’s and Microsoft’s online advertising businesses.

@CCC I don't get it. Weren't the cookie banners introduced just to prevent user information from being stored? I see 2 contradictory issues:
- you're not using a cookie banner - you're violating privacy
- you use a cookie banner - you are violating privacy

So how should it be? Or is it something else entirely?

@michal the issue at hand here is, that this ad system is handing over data by bidding and therefore cannot keep track of all the personal data it collected. Therefore it is in violation with GDPR, since the user of that data has no more control over it.

The decision itself has little to do with cookie banners. EU originally hoped that the GDPR would stop unnecessary data collection, but with a vast ad system in place, consent banners emerged on all ad-ridden sites and other people now use them pre-cautiously too.
