I fully support him on this, he has decided to stay away from some problematic kinks, it is the smart decision from his point of view as a creator, Patreon has a policy against games with non-consensual, loli or incest content, so far they have left him alone, but at any point he could get the ban hammer, and most artists don't survive the transition to SubscribeStar or other platforms.
As a consumer that sometimes enjoys that kind of stuff, it sucks a bit, but it is important to consider his perspective on this, it also seems like his patrons support him, so it is a no-brainer at that point.
