Me: "We terrified engineers into secrecy"
A lazy article to be sure, since it's all taken from Quora. There's some variation in the perspectives, because different people worked in different parts of the company. If you were in engineering, you had individual power even as a lowly coder. In any other department, not really.
I did actually talk to a journalist a few months ago about Apple's culture, but it seems that nothing came of that.
