He knew, why didn't he tell us how to avoid it?
funny thing about these is that it's actually the teams with women on them that tend to design and implement sexy ass vidya or 2D women into their shit.
A lot of women get their start in the vidya or manga business by doing porn, hell even companies Square Enix has a past in porn they try to cover up. And they aren't forced into it or have to do it as a passage right to get into an industry, they choose it themselves.
Making porn games and porn manga is easy because there's so little standards surrounding them, no one expects great work from you, and all it is is experience in making your own system of work to build on in less lewd environs. People do choose that path at first and ply their trade on the bottom and work their way up.
It's why a lot of animators and artists act like perverts, art starts at the primal level and a good artists learns to use that emotion to produce greater work while learning control of himself or herself. Art is a primal medium that relies on feeling.
