If Meta wanted to, they could've expanded it themselves. They didn't, hence all these other companies. Between MUI and Next and RTK-query, IMO, React is finally approaching something usable and complete. Not a React fanboy. I loved Angular v1, in fact. Just hate how minimalist and useless vanilla React was. Edit: And maybe this is a problem of scale too. At Meta's size or similar, React is just one component and one team that works alongside dozens of others to deliver a working product. But when they open source it, smaller companies and individuals also try to use it but without Meta's scale and resources. And they inevitably find it lacking because they don't have whole teams working on the rest of the problem (like basic routing, which Meta handles in their derivative of PHP, I think?) , so they have to hope someone else (like react router) solved that problem in a drop-in way. That's why Next is so magical for small and medium businesses; they do a lot of that curation and infra building for you, for a reasonable fee.
