Redux means everything is global state which is terrible. A grid I render now has to have global state and most projects forget to do any cleanup - so you end up with all this junk in redux that isn't needed anymore, clogging up memory.
I'm just not buying this argument. People add Redux to projects because they intend to use it, and there's almost never a case where a piece of data is actually needed in enough places that it should be global. It's certainly not common enough to justify importing a whole framework for managing global state.
