Well that's what is currently available, and what the author (somehow) thought would 'entice' the romance/dating sim/incest audience. He/she seems to have realized the problem with that and is at least making an effort to change it (with the different game-mode and adding/removing tags).
I agree, but I think even with the tag changes the complaining will keep happening unless the mc gets a way higher amount of the content ratio. Just because he choose a male mc and surrounded him with girls. Because unless the game is tagged as ntr, thats what people coming into these games are looking for and expecting. Not massive amounts of voyeurism content.
