I think it's because people are tired of the thrashing between/around the "next big thing." Angular was supposed to fix everything, React is still trying to fix everything... But even Atom stopped using React because it was so slow.
As for this framework, I'd be happier if it came in discrete chunks that you could wire together, because if you're not happy with one part of it, you don't have to accept it. You can instead build your own.

That's a mischaracterization -- it was only slow for a very specific usecase -- rendering a source code text-view. (It's like using an optimized C plugin in your python project for that core part that needs the benefit of performance.)
React makes a LOT of sense for a JS framework, and it's not a surprise that it's among the most popular ones now. To simply call it unusable because ONE particular usecase did not suit it is doing it an injustice.
Nice hearing that. I am currently working on making the framework more modular. This is create powerful individual modules that could be used for other purposes not only in MV* Framework.
