I agree. Also this article only makes it worse. It claims that (a) no one was working on Enigma before Turing and (b) Turing worked on it because he 'liked solitude'. WTF? Given that total bollocks in that part of the article I have a hard time reading the rest. Note that Bletchley Park does a very good job of talking about the Polish contribution to the cryptanalytic effort with examples of how the Polish attacks on Enigma were performed and a Polish memorial and they have a special annual Polish day.

Also, if the author wanted to talk about Bayes Theorem and the WWII cryptanalytic effort there's a much nicer example from the Japanese codes: http://blog.jgc.org/2010/07/bayes-bletchley-jn-25-and-modern...
