I never appreciated the popularity of redux. My impression was astonishment at the amount of boilerplate I needed for what I felt was a vanilla web ui use case. Then the required voodoo of hooking this up to someone else's clever thunk creation to make it work for common use cases. Compare this with mobx where we trust the developer to responsibility maintain state and just give them an object.
I'm sure it's useful for some folks with an unweildy amount of state to maintain but for most designs the overhead is too high
