That isn't the problem, the reverse is the problem. Meta generally has the right idea to offer a relatively cheap standalone headset, but the way they try to control everything on it, lock it down and try to establish a monopoly appstore with a huge cut makes it very unattractive for developers.
The few games that exist only on Quest are there because Meta bought the studio or directly paid for the development of the game.
Would be great if the future would be more open. The vr community has always been based on hobbyists with their open projects. It's incredibly unfortunate that there aren't any open headsets (free software and standards) Something akin to LineageOS for VR would be amazing. If not an entire OS, something like FOSS VRchat would be super great.
