Might be. But Team Ninja itself is not innocent here... The volleyball game itself baits these kinds of things. And if you start selling these overpriced costumes which look like laces pretending to be cloths... I mean, come on.
Aside from this, I really don't get why they make a big deal out of it. Street Fighter, Virtua Fighter, Fallout, Tomb Raider, they all have a bunch of nude mods and the list is endless, but you don't hear those developers complain about it. It's only Team Ninja that does this. Why?
