Good article. However if your adversary is a three or four letter agency then by all accounts it seems that PGP/GPG still does work. Snowden and Greenwald used it, apparently successfully after some tuition. The article also doesn't mention Bitmessage, which addresses a lot of the concerns. Bitmessage isn't forward secret though.
