He was sitting home from a concussion, recovering, not allowed to compete, and livetweeted Raws making fun of the product (granted, he could have been on meds and not fully aware that he was making fun of his employers' product while it happened). He's not entirely blameless here.
If WWE were really offended by that they should of fire him, he also isnt a yes boy coward either
this guy probably felt WWE officials didnt give a damn or reach to see how he was feeling
so he told them how he felt, alot of wrestlers don see the product from the outside.
I bet you CM Punk sees WWE worst than what he was seeing from the Inside
