Your personal expression is writing the open source software and putting it on GitHub. However, once you make it available as a service, you should be responsible for it.
Now, I understand that in the Kickstarted it was promised only the first developer kit and that it was successfully delivered, but I feel very uneasy knowing that the Facebook platform is geared exclusively to casual gaming. My worry is that Facebook will be happy with a VR technically good enough for a social VR but that can't stand the requirements for gaming. I may be too old to understand, but I really don't feel the urge to interact in 3d with my friends to say hello or to watch their holiday's pictures.
