A lot of the issues stem from the fact that Meta was backing React for so long (before it got purchased by Vercel), so it always had a ton of resources dedicated to it which helped win the mindshare. It's like that saying, "No one ever got fired for picking Oracle" or however it goes.

The other frameworks (except for Angular) are simply too small when compared to the massive coffers backing React. I mean, Vue is by no means small at this point, there are hundreds of contributors and people are making good livings off of the donations Vue receives, but it's still nowhere near React levels where Meta's full-time salaried employees got paid to work on React. It's a blessing and a curse to be a FOSS framework like Vue.

No React won and I choose it in 2015 because FB used it for their own app while Angular was by google but never really used by their top engineers so it was crappy. I think they still use Clojure compiler to this day. FB had correct incentives to keep it stable and good. Now that Vercel overtook I am more sceptical of incentive alignment
