This is just blatantly false. I've got several apps in production using nothing but React, React-Router and a unit testing library. In-fact I'd posit that it's easier to write good, maintainable code using a minimal toolset than it is to cram a bunch of rubbish in there that dictates your software's architecture. I've seen more people shoot themselves in the foot with things redux and redux-thunk than I have seen use them properly.
