I'm sure many people in hackernews value their privacy above $700, me included, but that's clearly not the point here. We're just a blip in facebook's radar.
46% for all Oculus types 36% for Vive+Index
Well, Oculus does seem to be more popular and perhaps that is what the parent meant by Facebook "winning" VR segment. To me "winning" sounds more like total domination, where any competition is near a statistical error. This doesn't seem to be the case here (though I admit Steam statistics may be skewed towards Vive/Index).
When I see people talking about Oculus dominination technology-wise, they mostly talk about the Oculus Quest. More specifically, a wireless standalone headset that doesn't require static captors to have 6 degrees of freedom.
Someone correct me if I'm wrong, as I only started looking into VR recently.
Oculus desktop software gives you a yellow mark, but games still work.
