This community is so freaking sad at the moment that I'm embarassed to be a part of it. I can here people now saying "GTFO if that is how you feel," but really, those who would say that just don't get what the core problem of this community is.
The quote above IMO examplifies exactly what is wrong with the community, that "we" believe that just because something seems/is relatively easy to execute, and seems relatively easy to understand, that that means everyone can to, and do it at the highest level, and therefore that isn't skill. Fact is that fighting games are not soley about execution, it's about reads, understanding/getting into your opponents head, understanding your tools, you opponents tools, understanding your skill set, and dealing with theirs.
People crying about Superman and his tool set are doing just that...crying. Yes Supes' zoning can be tough (not impossible) to deal with. Yes he can deal hella damage in the right hands. Yes his overall tools are some of the best in the game. But on the other hand, yes Superman can be beaten. Yes he has been beaten at the highest level. And no, Superman isn't broken because of it.
TL;DR
What KDZ did at EVO, and what he does with Supes on the regular, is nothing short of awesome, and those who try and detract from that need to 1) get a grip, and 2) level up.
