It's funny how that works. This story may be only tangentially related, but here goes: A few years back, I was visiting the local ARM offices in Trondheim, Norway. I happened to mention something about the iPhones using their processors, and my host immediately said, “I am not allowed to comment on that”. But everybody knows it, I said. In response, he said yes, but he still can't talk about it. Possibly, he broke the rule by admitting even that much.
I don't think it's strange at all. Consider for a moment, what competitive advantage does Apple have advertising that the iPhone uses an ARM CPU? The people who need to know the architecture can find out easily enough, the people who are just buying the latest iPhone know it has an Apple CPU.
Everyone and their dog has known that Apple uses Gorilla glass on their devices since the original iPhone. I believe it was only until recently (this year) that Apple executives acknowledged the relationship in any capacity (one of their SVP visited the Gorilla Glass factory with press)
FAANG NDAs can be crazy. I've been in a position where, yes, everyone knew something, and the other company openly talked about it, but because of the way the NDA was written there'd be heavy financial penalties for us to talk about what everyone seemed to know anyway.
