TBF, they should have worked the formatting so that it is easier to find for someone looking the said memo without having to scan through the whole article.
And the wording of the memo--quoting people and so forth--reads more like a news story than it does an internal memo. I had to go back through it to realize that the entire bottom section is a memo because memos are typically written in a single person's voice.
Frankly, when you tell a room full of people about something it's practically guaranteed to leak. The exceptions seem to be (a) secrets nobody cares about ("We're rewriting our ductwork design software!") and things that involve government secrets (and that doesn't always work).
I had a couple of housemates who were in the US submarine service. They never talked about what they did, even 20 years retired, and were very upset when the book Blind Man's Bluff was published.
Whereas I was at university with a guy who was previously in the Navy and was stationed on a large sub (name escapes me) and he claimed when they were at port and bored, they'd look into hotel windows where the blinds were left open with the periscope.
Hopefully for Apple's sake, he never went to work for them.
