How about all the data which map apps are asking for now (and in the past but for which they now have permissions): - WiFi network access (tightened up in recent mobile OS') which can give you a pretty accurate location - Photo roll (think of all that EXIF location data if you're giving photo roll access to leave images for reviews) - Calendar/location integration (who else is scheduled to go to that meeting on your calendar which you're directing yourself to via your maps app) - Bluetooth for all the BTLE beacons you're walking past in stores etc which have been gifted them for free from tracking companies I'm not taking a moral standpoint here on whether it's right to collect this data, just pointing out that there's an order of magnitude more than the article describes.
