His "point" seems to be that
A) Those old comic covers and panels are now being read into my modern minds to find different contexts and stuff in them. They're made so clean they're like the Match Game. Hence him pointing out the Superdickery site. Which ignores that that site is poking FUN at the the concept, purposefully taking the comics out of context and that some of those panels don't need help to read in an odd way.
B) On a grander scope, the concept became a self-fulfilling prophecy. The CCA forced main stream comic companies to get overly, squeaky, clean. By the mid/late 80s independent comic companies got more and more popular by not adopting the CCA and breaking boundaries. The independent companies became more popular and were threatening the big companies.
As a result the big companies over-compensated for decades of repression and trying to "out do" the independents by going to far, possible marring the "clean" images of the characters that had been popular for decades. It only got worse as the CCA became less and less of an influence and main-stream companies dropped it.
Really, I think we've still come out ahead.
