Based on Gunn's statement , it seems amicable.
Reportedly Gunn/Safran reported directly to Ellison post merge. Publicly Ellison said "Keep doing what you're doing". I'm guessing the rest of that statement is "...but we need more." Gunn/Safran and new head Jeremy Latcham have worked together before (on the first Guardians film).
It's entirely possible Gunn/Safran said they want to make films, put Latcham in charge, but that's pure speculation on my part.
