I don't think Carmack works that way. All he really cares about professionally (I'm not talking about his personal life or rocketry) is doing good work and pushing his code to the limits of the field. Oculus hardware was a big coding challenge without much marked territory or set rules for Carmack, so that's probably the only thing he was thinking about while working.

If he does, he's come a long way from the John Carmack that consistently open-sourced his 3D engines and followed up with developers who failed to abide by the GPL [0].

(I don't think he works the way you describe at all).
