Cm Punks promo real or fake?

I don't get why people are saying CM Punk could have used foul language if it was real lol. He used the f word on live television but they bleeped it out. Not to mention all the stuff he said about people kissing Vince's butt to get ahead and how HHH and Stephanie will take over. Either they are brilliant and they did this to kill pg or CM Punk really spoke his mind because he was leaving anyways. I know they used to swear back in the day on attitude era and usa network allowed it to go down they just bleeped the words, it's hard to tell if it was real or fake. I guess we will find out for sure next week.
