The irony is that there are a lot of "XYZ Native" solution, such as Flutter, Kotlin Multiplatform, Xaramin, etc. But somehow only React Native, something based on a web framework, seems to reach the critical mass.
I don't really see any cross platform framework hitting "critical mass". React Native is very accessible to web developers. Are you sure that is not just information bias from your own situation? For me, most cross platform solutions are a race down to the lowest common denominator (and this is from someone who has used Xamarin Forms and MAUI in production apps.) Sure, you get to use your favourite tech stack (for us it was .Net) and you get familiar tools and metaphors, but the overall results are very uncanny valley unless you put a lot of effort in to styling for each platform.
Probably because a lot of the knowledge you have over regular React transfers over nicely, plus being component based makes it nice, since you can import prebuilt components as a starting point.
