I'm sure WWE didn't be like "I want you in this video but not ___". They just got whoever was available to do the videos.
And its good that they have good and bad guys because it's not like fans see the good guys like cena,mysterio being the only ones sticking up for WWE, you see others like Del Rio,McCool,Miz and others talking about WWE.
Big Show was in one of those stupid things, and he didn't look too pleased about it either. He wanted to keep his job though, so he got on his knees and started sucking dick like he was told to, to help Vince's dumbfuck Republican wife. Remember back during his long break, he was trashing the company and said that Big Show was his "slave name"?
