What I don't understand about this whole kerfuffle is that Apple already had the power to arbitrarily block applications. Why not just make the TOS more explicit in requiring performant apps that look and feel like apps written in ObjC? That would still make life very hard for cross-platform flash, but allow people developing against Apple's library directly in Haskell, Scheme or whatever to do so.
