There are lots of other ML models built using training data derived from the public. Voice models, gait recognition models, WiFi mobility models, Bluetooth location models, activity recognition models, emotion models, etc. It's essentially impossible for people to tell if their data was used to train these models. And it's very difficult to know what companies and individuals might do with access to both live data streams and these models. Worth thinking about though.
