Talk about over-reacting!
It is neither libellous nor damaging, it merely points to a possibility. His near-term actions, or, rather, lack thereof, will verify whether he actually spends more time with his family, which IMO means not working at Poet.
He's been demoted/replaced - whether he was pushed or not, he likely did not want that to be his mark. So, it is very possible that he put an often-used gracious spin on it.
It's not like he has a pristine, squeaky-clean history with Opel/Poet.
