I would also guess they practically never use the App Store. In fact I would guess there's virtually no dogfooding of it at all internally, because they have 100k+ employees but need blogs to tell them when a sanctioned Russian bank's stealth submission is topping the free charts.
Who _is_ using the App Store these days? It's such a mess.
Does anyone use the App Store other than to search for an already known app name? I probably have not in over a decade, and I can't see a reason I ever would.
