I disagree. In a company with 10s of thousands of employees it still only takes 1 to leak something. Loyalty is (IMHO) far more important than those other factors (although they too contribute). Consider a more open example: Google. Internally Google is more open than I believe Apple to be (I have experience with the former, none with the latter other than what I've read). You may think that a lot of stuff leaks from Google based just on TC stories and so forth and while there are things I'm sure we could manage better, when I joined I was (and still am) amazed at what doesn't leak. Google doesn't have the same militant, even draconian, approaches to secrecy that Apple does. What they have in common is that most people in both companies (IMHO) are very loyal.
