I wouldn't go as far as saying that Google and Apple are actively deceiving developers. However, they do have a strong incentive to keep things the way they are, and to keep the end user ignorant of how the app economy functions.

You might be surprised to know that many customers on the App Store, and even some members of the press, seem to think that apps being featured by Apple have been bought by the company. I would get emails like: "how have things changed for you since Apple bought your app?"

If people knew how bad the app economy has become, there'd be far fewer app developers than there actually are, and the device makers would have a serious PR problem on their hands.

In the end though, I do believe that the short-term thinking I alluded to in my post will soon come home to roost. I do hope that Apple and Google course-correct before we end up in a situation where indie apps are a distant memory. It's in their long-term interest to keep the App Store diverse and the app economy healthy.
