Although I do not disagree with what is being said here, do not overlook the fact that Nintendo, as content distributor (WiiWare) and arbitre of several distribution platforms have a vested interest in downplaying the role of piracy. They are certainly not an impartial observer.
More than a content distributor, Nintendo is a major developer (via its numerous first-party studios) and publisher. While not an impartial observer, their businesses would peg them on the side of "any piracy is a problem" more than "piracy is not a problem".
