Guessing here, but I suspect they are referring to the revocation of the enterprise signing certificates used by gray-market iOS app stores, since native app emulators could only be distributed that way until now. It's whack-a-mole- the stores sign their executables with a new certificate, Apple finds out about it, revokes the certificate. When that happens, I imagine the software signed by that certificate will no longer run on the devices the software was installed to.
