After an abrupt exit by Instagram's founders, there have been reports that they weren't always happy with being seen as one of Facebook's apps, instead of a standalone platform. With curious timing, TechCrunch reports that at least one user, Jane Manchun Wong, has spotted a setting that would let Facebook use Instagram to build up Location History data from a user's phone.
Google does a similar history with Maps and using Android phones, and Foursquare's data business is built upon this model. Perhaps ironically, this is a bit of a return to form for Instagram, which sprouted to life from a location-sharing app called Burbn. Data showed that people liked sharing photographs more than anything else, and they developed Instagram to take advantage of that.
