Per https://building.nubank.com.br/welcoming-cognitect-nubank/, "Nubank does not own Clojure, just as Cognitect never owned Clojure. Nubank will take over Cognitect’s role as a corporate sponsor for Clojure, funding the core development effort".
I am pretty sure that whoever owns Cognitect is in no position to boss Rich around regarding Clojure. Besides, Clojure is rather simple and stable. No need to change it dramatically...
Now do datomic :-)
