This is Apple culture at its best: No one ever talks about it. All employees are so loyal to this company that you can't even imagine one speaking about such insights.
Loyalty? More like fear. I'm not saying that we should be privy to the inner-workings of every company, but a lack of transparency is hardly a culture worthy of praise.
Why shouldn't it be? Only cause people don't like it doesn't mean it is a bad thing... You don't have to put all your efforts and insights in blog posts!

I think it is more of fear about losing their job rather than loyalty. It is not uncommon to find that any leak will be tracked down and the leaker summarily fired.
