Revoking the certificate deals with the apps that have already been signed with that certificate. Google taking it down doesn't remove it from the devices where it has already been installed or prevent it being distributed by other means. Revoking the certificate does. In both cases Apple has reached an agreement to issue new enterprise certs for both companies. They can now use those certs for their approved purposes. If Apple finds that those certs are being used for disallowed activity they can revoke them again. I don't really see any issue with that.
