No.
The promo and the "voice of the voiceless" thing lasted what? four weeks? It lasted until around the time Punk won the title at Summerslam then got cashed in on by ADR.
What happened next? Kevin "Quadricep" Nash got involved and it looked like a feud between Punk and the Kliq was on the cards - ultimately it was decided to have HHH v Nash as it was percieved as a bigger draw. Given the writing in the build up to the match it probably was the right call - they could've built a match between HHH/Nash/Stephanie and Punk but ultimately creative went a different way with it. Fast forward a few months and the same thing happens again only this time instead of HHH it's John Laurinitis. This time they decided to keep the title out of the feud because they wanted Laurinitis to wrestle and, quite rightly, probably decided having him feud over the title made it a bit too cut and dry.
Raw 1000 Cena will cash in on Punk - Cena will win.
Summerslam Cena v Punk - Cena wins but controversially
Punk steps away from the title a bit - Raw has a new authority figure and "company man" John Cena is their favourite. Punk has proven he can be a good champion, now he needs to prove he can chase the title without breaking Kayfabe and still get cheered on.
