I'm missing the conclusion to that sentence. During 2011, the app store generated $3.4bn in revenue. Given Apples 30% cut, they'd see about $1bn revenue there, out of a total revenue of $108bn in fiscal 2011 [2]. That makes the app store about ~0.95% of Apples total revenue, compared to iPhone hardware sales, generating $47bn or 43% of Apples total revenue [3]. Now, you might argue that the app store accounts for some percent in that in that people buy iPhones to be able to play Angry Birds and whatnot, but from what I can tell, the most popular apps on iPhone are equally available on Android [4]. Pair this with the fact that iOS Safari seems to be the most capable mobile browser out there (or at the very least, in the top 2) [5] and I'm saying there's no published reason Apple would fight web intents or more powerful web apps in general.
Of course, I'm open to other interpretations.
