... because there's a group advertising that it's launching an open-source home automation control platform/protocol/widget. And naturally this is going to be the One Protocol To Bind Them All, there will be a grand unification (about as likely as North and South Korea unifying tomorrow, by the way).
The world does not lack "universal" or "open source" HA control protocols and products, it lacks manufacturers willing to support them, or even open their own control systems to support them. If there was such a thing as a truly universal protocol implemented by everybody, then manufacturers of hardware would be totally commoditized and competing solely on price/feature points. As things stand today, manufacturers profit by locking their hardware and software to work only with overpriced accessories and licensed "friend companies", and also by selling compulsory monthly service fees.
Oh, and that's not even counting the fact that approximately five people (and all hipsters, at that) actually care about home automation. Home automation is, always has been, and always shall be just five to ten years before going truly mainstream.
