If it was, they did us all a favour, because PGP as means of encrypting emails is a steaming pile of garbage, as it requires both, client support, and the counterparty to have the same OPSEC as you (e.g. not just forwarding the email unencrypted to someone else)
Email was never meant to be encrypted, and the existing implementations (including S/MIME) suck for this exact reason. And the worst thing is that it’s simply not possible to make it work.
