Facebook got called out publicly as its market research app Facebook Research VPN was blocked by Apple just before January ended. Apple said that Facebook was deliberately breaking the rules set down in Apples’ 2018 privacy policy change.

Josh Constine elaborates on Facebook’s controversial market research app in this report published in TechCrunch:

TechCrunch’s investigation discovered that Facebook has been quietly operated the Research program on iOS and Android since 2016, recently under the name Project Atlas. It recruited 13 to 35 year olds, 5 percent of which were teenagers, with ads on Instagram and Snapchat and paid them a monthly fee plus referral bonuses to install Facebook’s Research app, the included VPN app that routes traffic to Facebook, and to ‘Trust’ the company with root network access to their phone. That lets Facebook pull in a user’s web browsing activity, what apps are on their phone and how they use them, and even decrypt their encrypted traffic. Facebook went so far as to ask users to screenshot and submit their Amazon order history. Facebook uses all this data to track competitors, assess trends, and plan its product roadmap.

Facebook was forced to remove its similar Onavo Protect app in August last year after Apple changed its policies to prohibit the VPN app’s data collection practices. But Facebook never shut down the Research app with the same functionality it was running in parallel. In fact, TechCrunch commissioned security expert Will Strafach to dig into the Facebook Research app, and we found that it featured tons of similar code and references to Onavo Protect. That means Facebook was purposefully disobeying the spirit of Apple’s 2018 privacy policy change while also abusing the Enterprise Certificate program.

Sources tell us that Apple revoking Facebook’s Enterprise Certificate has broken all of the company’s legitimate employee-only apps. Those include pre-launch internal-testing versions of Facebook and Instagram, as well as the employee apps for coordinating office collaboration, commutes, seeing the day’s lunch schedule, and more. That’s causing mayhem at Facebook, disrupting their daily work flow and ability to do product development. We predicted yesterday that Apple could take this drastic step to punish Facebook much harder than just removing its Research app. The disruption will translate into a huge loss of productivity for Facebook’s 33,000 employees.
