The author submitted this on Reddit a couple days ago to /r/javascript, then deleted the submission after a very negative reception. That discussion is at https://www.reddit.com/r/javascript/comments/5a4irf/redux_is... . Looks like this is a second try in a different venue, I guess.

There's actually a bit of truth to the article title (Dan Abramov himself has said as much many times), but the article itself is rather short and kind of incoherent.
