@andy I just read The (extremely) loud minority, and wanted to offer a comment.
I really like the overall message; we developers tend to focus on ✨ the new shiny thing ✨ and sometimes forget everything else, stuff that's used by a majority of the web. JavaScript frameworks are one example and could be compared with sites that use vanilla JS or jQuery.
I don't know if your comparison with WordPress fully works though, because modern versions of WordPress all ship with React.
The React-based block editor was added to WordPress 5.0, so it's not all WordPress sites that ship with React. Still, given than more than 80% of WordPress sites run version 5.0+, that makes for quite a lot of sites.
With that in mind, one could say that React is used on more than 43% of the web.
I think your overall point still stands, but that caveat in your stats is worth noting.
