Apple leaves Facebook offices in disarray after revoking app permissions

Move comes after Facebook exploited loophole to harvest data about apps installed on people's iPhones

Apple has left Facebook's campus in disarray after the company revoked the social network's permission to build or run employee-only applications, according to reports. Employees were reportedly left unable to read cafeteria menus, call for inter-office transport or use versions of the social network's own apps.

The move came on Wednesday, the day after it was revealed that Facebook had allegedly exploited a loophole in Apple's approval system to bypass rules that banned the harvesting of data about what apps are installed on a user's phone. Facebook Research, an app the company paid users as young as 13 to install that routed their iPhone traffic through the company's own servers, had been built using an enterprise developer certificate (EDC) issued by Apple to companies that need to build applications for internal use.
