As other have mentioned, Vue3 is barely out, its still fairly new, and for the most part most people I know are also sticking to vue2. The pain of switching to vue3 might just warrant a rewrite in react.
For all of what facebook is worth, React has almost never broken backward compatibility, and the core idea has not changed much, while vue switched from 2 to 3 to adopt a more react like approach, go figure.
