Oh wait, stand-alone. I don’t know about that part. Google discontinued Daydream so that’s out too.

Arguably their reasons seem sound because how can they compete against Facebook in the consumer market with such a subsidized headset? Facebook is betting on being able to monetize your FB account and VR usage in a way that HTC can't with just hardware sales and software sales. Given that Quest requires a facebook account, it makes it a non-starter for enterprise/business use cases.
Facebook is poised to crush the rest of the industry. They have the cash, talent, distribution channel and brand to do it.
Innovator's dilemma happens when 1) a low-priced, low-feature startup takes on higher-priced incumbent. High priced incumbent ignores low-priced startup. No one can go lower than FB on pricing
2) Fear of cannibalizations (EV eating Gas-guzzlers for GM, BMW). FB has always let Insta, WhatsApp and Oculus to run like startups with plenty of freedom. Oculus is not a threat to core FB, but an enhancer.
Bottomline, time to load up on FB stocks
But yes, it's unfortunate that Facebook is killing them this way. The good news is that everyone makes a VR headset now, and people are writing VR games, so it will probably be A Thing even without Oculus involved. Innovator's dilemma and all that.
