For better or worse Facebook are the ones keeping VR on life support, without them it would have flatlined years ago. They have the only good affordable headsets, they throw tons of money around to bankroll VR game studios in exchange for exclusivity, and even for games they don't bankroll it's a no-brainer to prioritize their platform because >90% of sales happen there.

Even the minority who do buy VR games on Steam are mostly playing them on a cheap Meta headset, so without Meta those sales might not have happened either. The most recent Steam hardware survey shows that of the users who have a VR headset, nearly two thirds of them are using an Oculus/Meta model.
