He is kind of becoming a face with his "what are you gonna fire me" mode, and the fact that the fans hate the boss only solidifies his portrayal as a face. He can continue to use heel tactics and piss off the fans, but if on July 17 he's to be the ultimate face, why not build up as a face to MITB as well?
A little similar to Stone Cold's babyface character right now, going against the boss, exercising the US Constitution's 1st Amendment type of thing; this time around, he doesn't confront Vince face to face, but everything he says is true beyond a storyline.
