The problem with SteamVR and why Oculus chose not to support them is because it's being developed and controlled by a single party, is not legally able to be redistributed by third parties who aren't Valve, and is not open source. But note that there is a difference between OpenVR, the API, and the runtime, SteamVR. OpenVR is the one that is "open source" (though it's not truly open source). They are also not supporting OpenVR, because OpenXR is what they (and Valve) are working on instead.
