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.
It may also be a bit of a knee-jerk reaction, but in a world where even seemingly innocuous data is used to find unexpected correlations and identify people, I certainly prefer to keep a safe margin of error and steer away from companies which live on our data.
Besides, knowing Facebook's hunger for data, I certainly don't trust them enough to install any piece of their software on my PC. Nor do I trust them enough to use a device which could potentially identify some unique traits of the way I move in VR (akin to gait analysis).
