It's the precedent it sets. Censorship is insidious like that. First they come for the boobs and ass simulator and nobody gives a damn but by the time things "mainstream westerners" tend to like are getting disallowed it'd be already too late. You can't say "this one thing, this one is just vile enough that it's ok to censor it" because who is to say what is "vile enough". You may draw the line at this game but someone could draw it at something like GTA, someone could draw it at God of War. The only 100% surefire way to ensure that we can keep having the games we actually like is not allowing anything to be censored.
"Censorship" of that kind happens all the time, however, especially with content from Japan. A manga called Kodomo no Jikan was planned for localization, and shouted down by groups in the US because the main child character takes a bath with her uncle, something not unheard of outside the US. Nobody cared about that censorship or the precedent it set, they only care when there's SJWs involved.
Right there, just now, I lied to you. In fact it was opposed for its over-the-top and rather persistent and pedophilic themes, but it's an example of the way these things can be framed to manipulate people's emotions. Still, the point still mostly stands, first they come for the softcore pedo stuff, then for the grown up T&A, then we're gassing Jews for microaggressions. Slippery slope!
The fact is that no one is entitled to these things, the developer made a conscious decision not to release it in the west for what is probably a litany of reasons (anyone who honestly think business decisions like this are made on any one reason is a tool), it does not constitute insidious censorship, regardless of where the line for "acceptable content" is drawn.
