Great article and amazing work by EFF reconstructing the interface. I’m reasonably familiar with how mobile ad networks function. Am I correct in assuming that current iOS devices wouldn’t be subject to this because Apple has restricted access to a cross app identifier? Or is Fog/Ventel relying just on Waze data? Also, if you use pi-hole at home, wouldn’t that make the analysis much more difficult?
