But overall, I'm surprised how common the take is in the software industry that this is a fine state of things. How much of Apple's cut is because they run a good distribution network, vs. how much is because they are the only distribution channel?
Surely we don't think it's a bad thing that desktop software went in the direction of being an open platform (which, it's worth noting, may not have gone in that direction without DOJ intervention). Why aren't we rooting for the same on mobile devices, which have become just as essential?
