I'd say that the app store works best for relatively small apps and developers, where the 30% tax is worthwhile when weighed against all the infrastructure they would need to roll themselves. By comparison, Ableton, Adobe, etc, aren't having any trouble shifting units as it is, they have more than enough labour power to run their own infra, and they don't stand to gain anything by handing 30% of their revenue to Apple. Perhaps the question should be flipped, what would these companies gain from distributing via the app store?
