This seems like mostly the technical nitpicking that goes on with any crypto protocol. There aren't any holes here, and as a competent non-expert I'm having trouble deciding on whether any of these criticisms even rise to the level of a theoretical vulnerability. It's all best practices and hygine stuff. Which is fine, but hardly justfication for "Bad Cryptography".

I mean, these are the mistakes that everyone seems to make (including the blog author, who seems to have retracted one of the bigger claims). Stuff happens in engineering.

And the "GNU" angle is just bile, or a cynical attempt to get clicks by leveraging hacker political sentiment. Yawn.
