You can have decoupled Controllers from Views using React. That's the basis of the "original" Flux/Redux architecture used by React developers 10+ years ago when React was just beginning to get traction.

A flux/redux "Store" acts as a Model -> contains all the global state and exactly decides what gets rendered. A flux/redux "Dispatcher" acts as a Controller. And React "Components" (views) get their props from the "Store" and send "events" to "dispatcher", which in turn modifies the "Store" and forces a redraw.

Of course they aren't "entirely decoupled" because the view still has to call the controller functions, but the same controller action can be called from multiple views, and you can still design the architecture from Model, through Controller (which properties can change under what conditions) and then design the Views (where the interactions can happen).
