Right. And there's a big problem with "The Cathedral and the Bazaar" itself: it focuses on fetchmail, which is a relatively obscure (compared to e.g. Linux) piece of software that became remarkably cathedral-like in its development after ESR took over, to the detriment of its users.

(By "detriment" I'm referring to both design errors and numerous memory safety flaws resulting in remote code execution [1].)
