Facebook shut down its Research and Onavo programs after a report exposed how the company paid teenagers for root access to their phones to gain market data on competitors. Now Facebook is relaunching its paid market research program, but this time with principles — namely transparency, fair compensation, and safety. From a report: The goal? To find out what other competing apps and features Facebook should buy, copy, or ignore. Today Facebook releases its “Study From Facebook” app for Android only. Some adults 18+ in the US and India will be recruited by ads on and off Facebook to willingly sign up to let Facebook collect extra data from them exchange for a monthly payment. They’ll be warned that Facebook will gather what apps are on their phone, how much time they spend using those apps, the app activity names of features they use in other apps, plus their country, device, and network type.
