Then they stopped supporting desktop head mounted displays for the most part and switched to building face mounted VR computers that happened to have an initially janky, and always higher latency, passthrough mode to support acting as a display for a real computer.
What? There used to be a bunch of different VR platforms, and only recently has the industry settled on a single open standard, OpenXR[1], and Facebook was (or at least claims to be[2]) one of the major contributors to that open standard.
There are a lot of things you can criticize Meta for doing with Oculus, but opposing open standards isn't one of them.
For the first point, I'll give you that they prefer playing on their own platform. But they haven't "broken" anything. While yes you do need a software layer, e.g. Revive, you can still play steam games on oculus and oculus games on an index. And you have no idea whether that would have happened anyway as one of these companies got bigger.
Google used to say "do no evil" and now they don't, and they didn't get acquired before they changed. These things just happen.
With respect, did you ever use a Vive or a Rift CV1? They absolutely had much worst interoperability prior to FB. The launch of CV2 gated it behind the Oculus store, making it impossible to use Steam with the CV2 before overwhelming negative feedback changed it.
