Previously, Facebook relied on the Research application to pay users in exchange for their personal data, which caused a lot of controversy. Recently, Apple, which is particularly concerned about privacy, has put pressure on Facebook. Later, FB as a shield released a developer program for businesses (allowing for internal download of test apps that were not found in the App Store), but the iOS version of the research did not get rid of the fate of being shut down. However, the development of the conspiracy was not the idea of the birth of the variables. Previously, Apple confirmed that it had revoked Facebook's Enterprise Developer certificate because it violated the Enterprise Developer Program agreement and distributed apps outside of FO staff outside of an official store.
After the certificate was canceled, Facebook was actually much more hit than expected. The key point is that they have lots of internal tools that can not be used immediately. Verge has learned from his informants that the development of basic Facebook applications such as Messenger and Instagram are not working now. Even iOS apps such as a la carte and commuting used inside the FB have become inoperable.
In fact, Facebook at the same time as the offline version of iOS research claims that its own software has clearly expressed its purpose when it is attractive, and that those who claim to be "less than 5%" are teenagers and have obtained parental leave. But when using Enterprise Developer certificates to extend research outside of Facebook, they never had a reason to stand up. Apple and Facebook are in any case nervous about privacy. In the short term, it may be difficult.
