Putting aside our regularly scheduled pissing contest between pro-tag and anti-tag users, replete with personal insults and "<the other side> is the worst/obnoxious" etc...  
This was clearly intended as an incest game - the 'it's just a landlady and her daughters' (unless you have a 'patch') thing was a mitigation for the last bout of censorious shitwave that hit Patreon. That people who are fans of that kink are severely disappointed at that being taken away from them should be understandable.
Especially since it was on behest of a bunch of anti-porn crusaders who want to outlaw 
all porn. If you think they're only going to take away the kinks you dislike... well, you're either a shortsighted fool, or really on the wrong website 

.
(Which is also why those "those landlady/roomate stuff should just go away" takes...

 People don't create them because they just love pseudo-incest, it's because this was the only way to create (monetized) games with incest themes. You pretty much end up with "that kink shouldn't be in games, period", which I don't think you want 

)
And I'm pretty sure step-stuff has been verboten by Patreon for a while now.
