Advice if you want to work for Facebook: Don’t rock the boat. A Harvard student lost his internship with Facebook after provoking the company into updating its location sharing settings for Messenger.

Aran Khanna had an internship lined up at Facebook, but the Harvard student wasn’t going to sit around with his thumb up his butt until that happened. Instead, he got ready for his time at Facebook by creating a Chrome extension to showcase how the company gathers location data using Messenger’s Android app. The default setting meant anyone using Messenger for Android would share their detailed location data with anyone who they were in a message thread with, even if they weren’t Facebook friends.

He called the extension “Marauder’s Map” and it did exactly what he hoped: It drew attention to Facebook’s extensive location tracking. A lot of attention. People were freaked out by how closely Messenger could track your movements if you left its default location sharing settings on. Khanna wrote a Medium post describing his reasons for creating the app:


Within a day, Facebook asked Khanna not to talk to the press. He complied. Within two days, Facebook asked Khanna to deactivate the extension. He complied. Within three days, Khanna had lost his coveted internship. Nine days later, Facebook released an update for Messenger’s location sharing, so even though Khanna got screwed, his jettisoned summer gig resulted in an actual privacy improvement from Facebook.
