Motherboard reported last week that the U.S. military was buying location data that originated, among other places, from Muslim prayer and dating apps. The Motherboard exposé details how it happened: how the location data supply chain works, and, for example, how data brokers pay app developers to incorporate their frameworks into apps so that user data can be harvested and sold to buyers like law enforcement and military contractors. Developers may not necessarily be aware of what they’re agreeing to when they accept those frameworks, but they don’t have to embed data harvesting algorithms in their apps either.
