Patreon has purged a lot of adult games from the platform in the last few months and often for vague violations. TaffyTales had ~5500 subscribers (over 1000 more than this game) on their page when it got removed and they lost a majority of their income because of it. If the dev doesn't want to add incest then whatever its their game, but lets not pretend that it wouldn't put their income at risk.
