It's hard to say, because Apple is a huge corporation. It would be wrong for the takeaway to be "all of Apple is like this." But it should call into question "how much of Apple is like this?" and "how many more stories are there like this?" because I guarantee you that this author is not the only one who has experienced this at Apple, and there may be elements of its secrecy-obsessed, top-down culture that are common factors which contribute to it.
