My point is that the React marketing is "top down unidirectional data flow", and that you quickly reach the end of what you can do with that before needing to add a another perpendicular uni-directional data flow (which is Flux or one of its variants), which breaks the vanilla React paradigm and many of the simplifying assumptions implied within such a simplified system. Two flows, both uni-directional, but in different directions, and the top-down flow no longer has anywhere near the same degree of control once you've added Flux to your system.
