This seems wrong in many different levels. Not only React is getting faster, better, and more simple, but also is still the most adopted and the fastest growing web framework.
That's kinda like saying WordPress runs 40% of all websites....it's not really a testament to its quality, it's just what everybody knows how to build and deploy.
The difference being Wordpress is going down and React still going up. It's still the best business decision today and for the foreseeable future. It won't last forever, but the paradigm shift in UX that JS frameworks created will.
