It’s the first thought that crossed both Dan and Ben Volach’s minds after Apple announced Sign in with Apple at its annual developer conference this past June. Specifically, the part of the new feature that allows users to generate a random email address for apps when signing in, so they never need to hand over personal information to a third party.

A few days later, still reeling from the shock of seeing the technology they patented announced on the world stage, the Volach brothers’ email app, BlueMail, was removed from the Mac App Store. Coincidence? They don’t think so.
