Fully agree, Inversion of Control is not something which alone defines something as a framework. When defining it along the architectural axis React is architecturally unopinionated thus is has library-level scope, but framework-like control semantics. If framework = anything that uses inversion of control, then a lot of things suddenly become frameworks, including things nobody calls frameworks. One can call it a "rendering framework" but calling it a "web-application framework" is not factually correct.
