The Open Source Definition, written by the folks who invented the term "open source" a few months previously, doesn't say anything about the stuff Joe criticizes in Android. He's simply mistaken about the meaning of the term.
Also, the Android development policy that Joe criticizes is essentially identical to the way Emacs was developed up until the last decade. Emacs was the example "cathedral" in the original version of "The Cathedral and the Bazaar," for those who don't remember. It's well-established at this point, 13 years later, that bazaar-style development works better for a wide range of projects, but that doesn't mean that cathedral-style development doesn't qualify as open-source. It's just inefficient and frustrating.
