How common is browser fingerprinting when it actually comes to ad retargeting though? This isn't really the domain I work in so I could be off base here, but AFAIK none of the major ad networks use browser fingerprinting to deliver ads. Trying to use browser fingerprinting for ad retargeting/ad delivery would inherently be much difficult than with cookies (in most cases you won't uniquely identify users, and even if you were uniquely identifying a particular user how would you know?) and if ad networks were building profiles of users based on fingerprinting data they'd still be subject to GDPR and other related privacy laws. Obviously the technical issues and GDPR compliance are all things that can in principle be worked through, but to my knowledge no major ad network is doing this. |

Just like they currently are breaking the law by using non-compliant data processing consent flows (90% of the "cookie consent" flows you see out there don't comply), and how they broke the law for over a decade before the GDPR (turns out GDPR had prior art in most EU countries)?
GDPR penalties are not enforced anywhere near enough for it to be a deterrent.
