Oculus is between a rock and a hard place. The rock being consoles that want their own native VR solutions and aren't interested in sharing their cut of games etc and the hard place being Steam.
You just can't compete with Steam. It's been tried. All competitors are mercilessly drowned in the giant fucking moat surrounding GabeN's castle.
PC gamers are fiercely loyal, "generally" more informed then other consumers and absolutely despise any forms of dark patterns. Because Steam has always done right by PC gamers Steam has benefited from that loyalty for a good 2 decades now.
Everyone is welcome in GabeN's castle but y'all gotta pay the toll to cross the drawbridge.
Oculus has thrashed SteamVR, because the hardware side of things fell apart and the Quest 2 is a lot more like a console. It was actually pretty successful in 2021, Zuckerberg is doing his best to kill it with random rebrands and missing why people buy it (stuff like Beat Saber instead of weird replacements for the real world), but Vive/Reverb/whatever is nowhere
