I don't know what happened either and I wouldn't even be surprised if the parties have internalized it in ways that aren't 100% consistent. I do know that situations arise where it becomes mutually apparent that a parting of the ways is best for everyone concerned even if not explicitly stated. And, in those circumstances, there's a public story that is often not untrue but isn't the whole backstory either because it's simpler for everyone involved that way.
