1. Don't worry guys the update will come within the next month, DC announced that the progress will move very quickly once they finish the patreon patch and core changes.
2. Changing the names would not be enough for patreon to let them go the whole story is centered around a teenager living with his family so the game would still be seen as having incestuous undertones. I doubt that DC is just bsing otherwise he wouldn't implement anything that was voted on in stream or in polls. Either way someone will make a patch to restore the incest stuff.
3. If you play only for the incest and are disappointed, there are a lot of other games you can play to satisfy your needs, this website is filled with them (also I'm surprised that you would play only for the incest, that's kinda dumb, the art and story are so well done and you decide to focus on something you can find in almost every other lewd game...).
