Unpopular opinion: although I hate how oculus sold out to Facebook (possibly backstab of the decade, after the initial crowdfunding), and although I’m a strong advocate of leaving Facebook regardless of their VR BS, there’s really nothing wrong with them requiring a Facebook account to use it. I have no idea how much the manufacturing/R&D costs of Quest are, but I doubt it makes sense for Facebook to sell it this cheap without requiring users to link/create a Facebook account. Don’t expect stuff to be free/cheap for no reason.
My point is that regulating this space of tech will only lead to less innovation. There’s an extremely easy solution that every single one of us can do: don’t buy it, don’t be tempted by the cheap price Facebook is offering. I closed my Fb account ~5 years ago now (after being on it for about 10 years) and I’m very tempted to buy Quest 2, but I won’t. If enough people do this, what ever scummy plan Facebook is weaving will fail, but even if it doesn’t, you’d be out of it.
