I think transparent kinds can be explained by the concept being simply cool. As for enclosed VR style headsets, I really think Quest must be actively being used by some non-negligible numbers of users for purposes considered career-unsafe to mention that isn't pornography, by which I mean VRChat. This pink elephant theory can explain paradoxical continued presence of Quest inconsistent with apparent total flop status, especially contrast to actual total flop of AVP.
