I don't know why exactly you're getting downvoted but I completely agree. React was designed for increasing the maintainability of large, extremely stateful SPAs. A blog has barely any state at all, and can be served statically from HTML. There seems to be almost no reason at all why a blog should run any javascript client side, let alone a whole library like React.
