Romero is an ego maniac who believed in his own legend to the point of self destruction. He has always been more interested in his own image than games. It's all in the history of Ion Storm. An office at the top of the highest skyscraper in Dallas that "featured a ten-foot-wide company logo on the floor in Italian marble." He hired his girlfriend, Stevie Case, to do level design. The whole 'design is law' bs. His hobbies included spending publisher's money and racing Ferraris while his games turned into crap.
It's funny that he still wants to be taken seriously as a game designer, when his company produces ports of games for mobile phones. I'm sure he'd much rather be remembered as a serious game designer rather than an epic failure. Hence his "sincere" game design podcasts.
All in all, Romero is the last person that should be criticizing games, game design, work ethics, publishers, etc. Wilson reminded him of that fact, and reminded us all what Romero really is.
