Apple developers policy was breached by both facebook and google. In return the might apple revoked facebook causing the major downtime experienced yesterday, 31st January. In the same line of duty, apple has also punished google for the same. The move came in after the two major firms used the same special access for market research.
Google of late has been doing something similar to that of apple by making the gui similar to that of IOS. This made apple to revoke the move hence canceling the certificate.
