Punk has always said that he and Vince had/ have a decent relationship and I recall a report that Vince didn't want any hatchet jobs done on him. Now, that's probably more to do with Vince knowing that Punk is super popular and sells a ton of shit so why burn that bridge....and I'd guess that Vince has a respect to anyone who stands up to him and has a lot of balls. Especially since Punk just retired, the days of him being mad cause they went to the "competition" are gone.
