We don’t know whether Apple’s apps will ask yet do we? Not until the next iOS update.
And when an app doesn’t ask, does that just mean there is no tracking going on or is it some nefarious scheme to achieve who knows what?
The nefarious option will probably become most popular on the interwebs, obviously. I can already see the HN posts: “Pages caught loading an asset from apple.com, violating their own tracking policy! Is Apple doomed?”
