VRChat came out more than 5 years before Horizon Worlds did, and already had an established player base by the time Horizon Worlds even came out. It was in early access for ages, but that didn't matter to the VR audience, who's used to there being jank. Not to mention that Horizon Worlds was probably never more of a finished product than VRChat to any significant degree.

If you've already got a VR social space, why switch to a different one?
