I agree if the Dev likes NTR and Majority of players like NTR then he should do it and players that don't like it should just go play another game. There is plenty of games that don't have NTR. But you also have to think of it this way if there is not many people that like ntr then not to many people will play it. And sorry to say but people that like NTR is a minority. So why put so much effort into a game that only a Minority would only play? I wouldn't. You can see for your self that NTR games usually don't do well and the ones that do usually have it optional or avoidable. I myself hate NTR or swinging or anything that has to do with my woman or potential women having sex with anybody but MC.
You said it, the developer likes NTR, that why he put such effort in the story, I never saw anyone asking "why this developer is making an harem game?", the answer would be the same, because he likes it and because he want it that way. The developers should tell the story like they want, if the initial idea was that the game had heavy and unavoidable NTR, and that some guy blackmail the MC's girlfriend and then fuck all his friends and family, the developer should be able to do it without people bitching or telling if they like or not NTR or asking the developer to make it avoidable.
If then the developer thinks, "I'm not doing well in patreon, I should change the game to harem or with avoidable NTR or maybe quit this game and start making other." So be it, but most of the time they change the game or quit because people bothers them in every post, and none of those critics is constructive, always they complain or make a remark about the NTR and that they won't play the game until is avoidable.
And again, you said, there are tons of games without NTR and still, when a NTR game is released there is always someone that go to those threads and start to complain.
