If customers buy a game from us, I don't care if they mod it to run on whatever they want. As I have said a million times (and counter to the current circlejerk), our goal is not to profit by locking people to only our hardware - if it was, why in the world would we be supporting GearVR and talking with other headset makers? The software we create through Oculus Studios (using a mix of internal and external developers) are exclusive to the Oculus platform, not the Rift itself.

The issue is people who expect us to officially support all headsets on a platform level with some kind of universal Oculus SDK, which is not going to happen anytime soon. We do want to work with other hardware vendors, but not at the expense of our own launch, and certainly not in a way that leads to developing for the lowest common denominator - there are a lot of shitty headsets coming, a handful of good ones, and a handful that may never even hit the market. Keep in mind that support for the good ones requires cooperation from both parties, which is sometimes impossible for reasons outside our control.

On another note, I disagree with most of your post, and I think you are either misunderstanding or misrepresenting several important points, but that does not change my answer.
