No they aren't overlooking it. They literally call out the additional net value created (i.e. iPhone hw sales), and then call out that to make the enormous amounts that they do make, they also crib value from others (i.e. app store).

You can argue that the app store and vetting process itself is worth up to or over 30% (i.e. they are giving value away, not extracting it), but they make a clear distinction.

Overlooking was the wrong word. I meant more like downplaying or underestimating. Uber completely changed transportation, and the legal saga that follows shows just how big of a change they made on the world, for better or worse. Likewise with Apple and the iphone. They created (or popularized depending on how you want to frame it) the platform that now dominates the human condition. We are literally fumbling, on a global scale, with how to interact with our phones because of how much influence they have over us.
