If anything, what I've seen is the opposite concern, which is that app stores make prices too favorable for consumers, at an untenable cost to the developers.
But it’s easy to make across the full ecosystem of digital app stores which are near universally 30 percent rakes. I’m including games in that list; Xbox, PlayStation, Steam, etc.
That said, even if mobile apps are cheaper than they used to be many could be even cheaper if Apple took a 10% cut.
I don’t like living in a world where almost every major distribution platform has complete vertical integration. The 30% cut is a farce. But I’m not sure this is the best argument to end it.
Compare that to apple users. As a start, you'd probably have to convince those to buy a non-apple device. That's a huge barrier to entry. It might be justified, i you believe that's good for other reasons like security. But then we're far of from driving down app prices.
I want fine grained competition. It is what makes our economy more efficient. Market leaders in contrast don't want to compete on profitable parts of their business and as such, will employ any tactic possible to stop that. Like e.g. placing barriers to entry (see above). Or make it difficult do make informed decisions (stores reads quite a bit like printers and overpriced ink). Thus I have a hard time buying into those "this is for the good of the consumer" talking point.
It's interesting because I imagine that'll be Apple's argument, and the natural counter-argument is that the $0.99 price is deceptive because of the "freemium" model of most apps.
Not sure how convincing they can make that argument, but it'll be interesting nonetheless. I imagine it'll involve putting an average "cost-per-app" including in-app purchases.
It’s often followed up by claims that they could do it thenselves for much less in much less time, ignoring the realization that that is only possible because the original developer has done all the hard engineering and design work, and worked out how to make things fun, etc. (my most obvious memory of this was when Threes came out and it was instantly cloned by people who had full access to the game design)
