You know, there was one part of this song that always fascinated me, and it's the part where the singer addresses the person she's speaking to, saying, "Is this really want, you idiot? To just sit around reading shonen manga?"
At the same time, Anno has claimed that he wants to help revitalize the anime industry. I'd almost write it of as the people who chose the ending song just didn't pay attention, but I'd like to think that there's more to it than that.
Kinda like how nickelodean will run that ad during the summer telling you to go play outside.
