As much as I dislike Punk as a performer and hell, even as a human, he did the right thing to walk away. Why risk getting wheelchair or casket bound while the paychecks are shrinking and while the bosses clearly think you're a piece of shit? Why work for a corporation that doesn't give a shit about your health because they need to make a quick buck out of you? Why say anything even remotely good about a corporation that sent you termination papers on your fucking wedding day?
Is Punk a douche and sometimes delusional when it comes to some things, i.e. The Rock? Probably, yes. Has the product suffered without him? Probably no, idk, I don't watch regularly. But if I had to choose between a clearly malignant double-standards-happy corporation run by backwards lunatics and some emo douche, I'm siding with the emo douche.
