Yeah, unfortunately NTR is always a super touchy subject for people, for whatever reason. I've seen extremely heated comments and/or trolling over everything from the very definition of it to demanding it be added to or removed from a game. Most people tend to either absolutely love it or absolutely hate it. I'm personally fairly neutral on it.
I'm also of the mind (as I've said before) that you, as the developer, should do whatever your vision of the game is. If one's purpose as a creator is to get famous and independent quickly, one ought to identify going trends, find something unique to bring to the table, and then develop based on these principles, paying especial attention to feedback received. If, rather, your purpose is to develop a game because you have a story to tell and want to share it, regardless of its reception generally, then stick solidly to your vision. If you can manage to do the latter and gain a large following, obviously you're in developer heaven.
