Nothing exists in a vacuum.
I'm not a fan of Chrome, or some of the choices they made for ChromeOS, but if they're willing to provide "proprietary" hardware APIs, that are fully documented and open-source, and can be used free of charge, and free of mandatory centralised control mechanisms like on iOS, then I'm all for it.
Mozilla had the opportunity to do the same with Firefox OS; but, of course, now they don't quite have the resources to do that anymore, so, instead they get to tell us that we cannot have nice things?
