The _sellers_ want an alternative to iOS and Android. A possible reason why none exists on the market--at least not with significant numbers--might be that the buyers don't want it. More precisely, buyers don't seem to want anything that sellers are able to produce at the price they'd be asking for it. I'm not sure what are the proper rules to anthropomorphize the market, but I'd say that for the market to "want" something, you need sellers to produce something at a price which buyers are willing to pay. You've got a polished and tightly controlled garden with iOS, a commoditized ecosystem in which to find commoditized phones with Android, and a base to develop one's own walled garden _a la_ Amazon, again with Android. There's nothing very exciting for non-Apple sellers here indeed, but that's a pretty good situation for buyers; I can't think of a buyer problem which would be best solved by a completely new OS.
