But that's the thing with the GDPR, the potential fines are quite large.
If someone has the will (and I'll admit it's probably quite a big if) then this sort of case could cause some massive changes of behaviour in the tracking and advertising industry. Probably just for European end users though. It will either cost a shed load in fines or a shed load in lawyers fees (and then hopefully a shed load in fines on top! - Hey, I can but dream)
