Know this scene where Spencer attempted to sell Rick down the river to Negan in exchange for some pull? Negan didn't like Rick but viewed Spencers tactics as cowardly and weak. Only people he had more contempt for outside of those who got out of pocket were cowards. He didn't like Rick, but he respected him.
Vince is a bizzare individual. He doesn't operate like most folks. Ambrose honored his contract & while he wasn't placed as high as his Shield mates, he was still clearly a guy Vince frequently turned to and had it better than 90% of the entire roster. Vince didn't do him nearly anywhere close as badly as hes done other talent on their way out. Wouldn't surprise me at all if Mcmahon -- in his mind -- felt repulsed by Rollins burying his nose up his ass and attempting to throw Ambrose under the bus for brownie points.
Not because he said anything Vince didn't want to hear, but that he smiled in his face and waited to bark until
after dude was gone.
Vince has clearly been burying Rollins ever since. I'd like to think he believes Seth is just as much of a sniveling p*ssy as others do, but its likely just shytty booking as usual.
