Except perhaps for any high profile Apple device attached to the App Store (the case in question). Almost every mainstream site has verified mobile Webkit compatibility and/or dedicated applications. The group of people who still need Flash in that scenario is small enough that leaving it out wouldn't likely have a measurable effect on adoption. For a web product from a company that can't command as much market attention, shipping without Flash might well be a death knell. But Apple's different. The App Store is different.
