TL;DR click bait. The author is replacing Redux with Apollo - a client side graphql library that HAS BUILT IN STATE MANAGEMENT, which he fails to differentiate or mention... Apollo is similar to the firebase event / subscription model.
I reread it several times trying to understand how simply using GraphQL allowed you to eliminate the need for all actions / stores for your entire client side stack. It wasn't until I looked into Apollo that I understood what you had actually implemented.
Apollo is mentioned 4 times in the article. That's beside the point though, even using GraphQL with plain old HTTP requests would have removed a lot of the need for Redux in our case.
