Error in #8. OpenXR releases and everyone may use a single SDK, but the runtime will go to whatever the headset needs it to be, so the Oculus runtime will be used when it should again even on games developed with the SteamVR SDK.

I tried not to demean but come on, I'm just trying to explain things here and using proper English on top of it all... Anyway,

>It's fucking VR, and what works on valve works on Oculus
Again, it's not so easy! A lot of SteamVR games did not always work so well on the Rift, and things had to be patched to work on both. Even the controls imply that you kind of need to develop your game with different headsets in mind or else you force the users to try and map the controls themselves. 

>If Oculus people hate their store so badly that a game being on both means they go to SteamVR then it's a problem on your end that needs to be fixed.
That kind of a world would be more fair to these businesses, but it's not actually how things work. Even if the Oculus store was the exact same as Steam, with the same UI, UX, etc, people would still be buying from Steam because they'd rather have all their games in a centralized location (even if centralization is actually a riskier and worse idea, it's more convenient to them in the short term). It's not that people are installing Oculus and then installing Steam because they notice it's better, but because they had Steam installed already and would rather not purchase games on another store if they don't have to. And then there are people who hate Facebook, who want to minimize the amount of money they give to them.
