It's reverse psychology. No 'integrated member of society' can be seen to be enthusiastic about animated T & A... it's unhealthy. The sort of thing that would get disparaging column inches in the News of the World, I mean The Sun on Sunday.
So you have to be seen to be adult about it, bemoan the state of the industry. Oh how terrible that these maladjusted individuals who cannot possible have healthy human relationships have to rely on this sort of thing to get their rocks off.
But the point is that by doing so, they are getting the info out there that HSOTD and it's ilk are loaded with fanservice. That's the message that gets through to the fans, job done, and as has been said on occasion, no such thing as bad publicity.
