Anecdotal evidence from my experience finds this to be true but only when you consider the type of developer and his field.
Opensource web oriented platforms (i.e web developers who commit code to web based projects in accordance to open source code licenses) use OSX in my experience by overwhelming majority.
Lower OS Level developers tend to stick with Linux or BSD
In some instances it didn't make any sense at all, the pains I saw developers trying to install couchDB on their OSX platform (i think it is a easier now), it was far easier to do this on ubuntu.
Developers also have aesthetic impulses, and OSX looks good and feels good, for most people, better then any X based GUI other platforms have. This is also an issue with the relative comfort different developers have with the Terminal.
Much can be said about this practice, no dog fooding might make open source less viable in the long run.
