This is one of the most wholesome uses of location data I’ve heard about. There was a NYT article a few years ago about the data brokers who sell this info, and how easy it was to deanonymize if you know where a specific person is at certain times. The journalist did this using Trump as an example, matching the location data in reports to where he had been seen on live tv. https://www.nytimes.com/interactive/2019/12/19/opinion/location-tracking-cell-phone.html https://www.nytimes.com/interactive/2019/12/19/opinion/locat... I am really curious who else buys this kind of data and what it’s used for. I’ve heard commercial real estate owners have also used it to track how many people are returning to offices so they can predict what their tenants will do when it comes time to renew the leases.
