I hear it thrown around a lot that Cena has enough clout to say what he will and won't do as far as the ideas that creative bounces off of him, but imagine you're in his shoes.
Would you really tell your boss that you didn't want to be the face of the company?
Would you really reject an idea to get another guy over?
Would you really walk away from all the money that Cena makes simply to make a small section of the fans happy?
The IWC hero CM Punk has even said that he wouldn't walk away from that if he was given the chance.
John Cena is one of the best talents in the wrestling world right now, and for him to walk away from that simply to please us just isn't going to happen. So he is going to continue to be booked as a Superman character who can beat all odds and always come out on top.
The WWE brass wants their top guy at the top, and that's where Cena is going to be for quite some time.
