I hope people don't read things like this as advice for things they could recreate at their own companies. There are lots of others way to be successful without being outright mean or vindictive.
I honestly am surprised that there are so many intelligent people who are willing to put up with this sort of environment. I really like Apple products but I'd be out the door in a flat second if I was working there and experienced the kind of culture described. Life is too short.
