i mean, that's cool if you want to own the libs like Big Ben, but what the customer base is saying is "this part of the art is a turnoff, please consider rerendering it" and no cool comeback in the world is gonna change that sentiment.
if i drew erotic art where the genitalia of a character looked like a pus-oozing worm-infested fleshwound, people would be right to point out to me that that part isn't generally thought of as attractive and might deter otherwise engaged audiences from supporting my work.
You may be right that they are alienating a large audience of people looking for more normal body types, but you also have to remember that there are plenty of people that specifically search for non-normal body type porn games because they want something different. That's why there are porn games with furry characters, aliens, monsters, and even body morphing. Those are fetishes that don't attract the most people, but for those that do enjoy it, it's great.
At the end of the day, this is a game about a fictional race in another world. If the creator made all the races and body types conform to Earth standards, then they'd be leaving a lot of potential un-explored. Fantasy demands variety.
