It seems to me that this approach of the developers is connected not only with the rules of Patreon. Not everyone likes the topic of incest; for some, it doesn’t matter if they are related to 2 heaps of pixels or not, but for others it is taboo. For example, I do not accept NTR, cuckolds and transgenders. And it’s very good that we can choose. At least I've come across games where the player can choose acceptable playing conditions that have little effect on the plot. I always want to say thank you to such developers.
