I don't think the operating system to connect the worlds drones is going to be closed source. 3DR and their open source base is going to give Airware a run for their money as the de facto standard "operating system for drones" in the consumer and more and more in the commercial space.
In the meantime people like Drone Deploy and Skycatch will fill the gap when it comes to data collection and processing which is where the real business is long term. Drones themselves will continue to become a commodity. Also, it's worth remembering that a Chinese company, DJI, has about 80Pct market share in the US for consumer and prosumer drones. Lots of competition for everyone.
