i mean, i get it Patreon is where these devs get compensated for their work, i fully respect that but there are other devs that give us patches or work arounds (like letting us manually type in the relationship of the characters like Landlady or mother and roommate or sister)
It's called playing it safe. What do you think will happen when the moral police takes another step? And it will happen, these kinds of "holy warriors" don't usually stop half way. Then those other devs will be fucked. Some may be able to succesfully claim that they didn't do anything and it was some anonymous fans. But for others it's pretty obvious that the way around the rules is their work.
But good news, sort of, if you really want incest very much, it's technically not too difficult to modify game files. Nothing special is required, you can simply change strings using any hex editor. Just make sure that the new ones fit within the lengths of originals, i.e. what you use must be same length or shorter, otherwise you damage the files. There's probably other way too, which would allow even longer strings, but the files would have to be recompiled or something, but I don't know what the used format is.
Here's a little test, I just replaced occurences of "childhood friend" with "cousin" and few other things. It's just to show that anyone can do it,
I do not plan to maintain it. It would have to be redone for every new version. Although if someone took the time to find all strings that need to be changed and posted both old and new versions (whole strings) and in which files they are located, it shouldn't be too hard to make a patcher that could work even with future versions (as long as the strings are not changed by author).
