I wish that was true. If that was the case, I would've bought a headset from a competitor in a heartbeat.
Unfortunately, while there are many competitive VR headsets out there, I cannot recall a single other VR headset that works standalone without a PC.
Not even mentioning the price point of Quest and the fact that it can be used for both PCVR and standalone, thus bringing a superset of features of other headsets. No need to set up lightboxes and being able to just buy the headset and play without anything extra is a value proposition that I don't see any other VR headset can provide.
Hopefully, the success of Quest will provide a kick in the ass to other manufacturers to make their own versions. Imo, the standalone+PCVR combo with no lightboxes is the future, with lightbox PCVR-only headsets being reserved for highly niche uses.
This is absolutely the hill to die on. Oculus has competitors. The answer to save VR isn't to buy Oculus, it's to buy other headsets and hope Oculus dies unless they reverse their decision to require a Facebook account.
