Oculus and Vive developers don't create VR experiences using Microsoft tools, and headset owners don't buy VR software from Microsoft's Windows Store. Facebook (owner of Oculus) and Valve (partner of HTC) have their own storefronts and their own tools, which means they stand to make the money from the VR ecosystem, until or unless someone else comes along.
