Fingerprinting has been a huge bone of contention in our new iOS 14 world of IDFA scarcity. Is it allowed? Is it not? If so, when?
The reality is that some vendors have placed huge bets that fingerprinting is still OK. That it’s fine, and that mobile marketers can still attribute mobile app install campaigns with device fingerprints. Especially, of course, if we call it a much more gentle and benign-sounding name: probabilistic attribution.
After all, it’s just probabilistic, right? A fingerprint does not identify a single device or human being with 100% accuracy. So it’s private, right? Kind of? And Apple will be OK with it right?
Not going to work.
