DaveyJJ sends news of yet another rejection of an iPhone app by Apple, with perhaps a chilling twist for potential developers of productivity or utility apps. John Gruber of Daring Fireball writes: "Let's be clear: forbidding 'duplication of functionality' is forbidding competition. The point of competition is to do the same thing, but better." Paul Kafasis (co-founder of Rogue Amoeba Software) makes the point that this action by Apple will scare talented developers away from the iPhone platform. And Dave Weiner argues that the iPhone isn't a "platform" at all: "The idea that it's a platform should mean no individual or company has the power to turn you off."
