Gutmann writes a bit colloquially, and the text was a message on a somewhat informal mailing list. So keep that in mind regarding the tone. The overall point of the post was not to blast DJB, but, well, to point out the crypto monoculture, like it says on the tin. DJB's stuff is good, which is why it is popular. The problem Gutmann is highlighting (mostly) is that nobody's competing with him. That problem? Monocultures are high-risk. A bug or a cryptanalysis breakthrough could render "everybody's" security broken at the same time. Or, DJB is eaten by a bear; who supports that code now?
