I think it is obvious that company X tries to minimize their competition as much as possible. However, when a third party like Gamastutra starts to claim that the competition itself is the problem we have a problem. Besides revealing a terrible grasp on economics, it begs the questions what these companies have sold us before they discovered that competition indeed exists? Isn't that basically admitting that they have sold us crap?
The issue is devs have seen this before on the mobile app stores, good shit gets drowned out by the flood of banal crap. Awareness of product is as important as good product in the digital age, that's why EA spends millions on marketing. I don't even check the Steam new release list anymore because it's filled daily with shit I don't care about. I rely on the Codex and similar sites to tell me what's coming out that has any merit. Most people aren't lame enough to post on here though, so some user curation would benefit them. "Benny's RPG Store" could highlight all new and coming RPG games and then I could basically just check that and log out.
