Bourdain had an 11 year old daughter he loved dearly and the same with a girl friend who he was in love with. Also his new show had taken a turn toward more news,less food and CNN was freaking out.They could not control him since he was the only good show they had on the entire network.More likely he pissed the wrong people off and someone got to him.
He had investigated Hillary,made a few comments about her and her aids told him to eat a scorpion, CNN,he was all over deep state pedos, he was chatting for days with Elon Musk about the deep state which he was recently awakened to(hopefully not stoned out of their minds but you never know) and was after Weinstein.
Too many irons in the fire.
He had rattled too many chains and one of them acted on him pretty safe bet.
I agree, Tony was a lot of things, Liberal, Snarky, but he was no quitter.
