You're being pedantic. It's a distinction without a difference. The OP said, "AppStore came out of iTunes and has always been part of services under Eddy Cue", but it's actually been a very long time since Cue was in charge of the App Store. Schiller became the head of the App Store while he was still SVP of marketing and continues to be the head of the App Store today.

App Store is absolutely organized under marketing at Apple. Not under Joz, as I've already said, but under Schiller. Both are marketing. "Apple Fellow" is a euphemism, a term of marketing!

If I would have said on August 3, 2020 that the App Store is within the marketing department, there would have been no dispute. The only change on August 4, 2020 was that Schiller gave up some of his responsibilities to Joz, but Schiller still retained some, such as the App Store.

App Store is not under Eddie Cue and services. It's not under Craig Federighi and software engineering. It's not under Apple Product Security. It's not under Jeff Williams and operations. What would you call it, if not marketing?

For reference, Schiller became head of the App Store in 2015: https://techcrunch.com/2015/12/17/apple-promotes-jeff-willia...
