Perhaps it is vendor lock in, but the concept as a whole is not that difficult to generalize, as other frontend frameworks have their own sorts of implementations of the concept. Phoenix in the Elixir world has LiveView, for example. It's just that React's is more seamless, especially with TypeScript, as you can run JS (TypeScript) on both the client and server, so that you have greater control over exactly which components you want to be on the client versus the server without having to do so manually if you were to use something like Rails or Django. Therefore, even if you are making something like blogs, you can still use React as essentially a templating language via JSX and also use React for interactivity, for example a comment form component.
