Thousands of Facebook employees have lost all access to internal iOS corporate apps because Apple has revoked the company's enterprise license that allows Facebook to develop apps outside of the Apple App Store for internal use only. This has caused widespread panic at the social media giant as employees are unable to use their iPhone devices to open iOS beta apps in development and other apps such as the lunch menu and transportation. Facebook ran a scheme to pay teens and others $20 a month for the right to data mine their phones using an app that violated Apple App Store rules. It circumvented the Apple App Store rules by using its enterprise certificate from Apple to develop the apps that used a VPN to track people's phone activity and web traffic in exchange for money. To further hide its rules violations, Facebook instructed victims to sideload the Facebook Research app onto their iOS devices. Apple says the enterprise certificate is only to be used to develop apps for a company's internal use. Since Facebook blatantly broke the rules, Apple revoked the company's enterprise license.
