Alright, fine. WebVR predates OpenXR by about 3 years. When WebVR was renamed to WebXR, OpenXR existed in name only, and nobody knew if, once the spec even came out, it would get adopted. It wasn't a well-known name at large by that point, and there was significant concern from the W3C to avoid confusion with creating separate WebVR and WebAR APIs. So, "they should have been careful to avoid confusion with OpenXR" gets it backwards, over-assigning the ownership of "XR"-named things to Khronos.
