I heard that fen actually asked patreon about a bunch of the niche content in the game and got the green light from them. As far as I'm aware, though, that was a while ago, and things seem to have definately changed a bit.
Patreon is essentially being pressured by it's new partner PayPal to crack down on the taboo content. Which is likely why fen took preemptive measures and didnt/isn't trying to work things out with them, cause they aren't the ones actually calling the shots.
Also, if my own experience has taught me anything, it's that sometimes, pressing the issue only makes things worse. Fen could try and get the green light from Patreon once again, which would solve the problem easy, but hes likely afraid that doing so will draw attention to it all and get them in trouble. Plus, there is the possibility of further changes and crackdowns by PayPal down the road, which would end up screwing them anyway.
Im trying to look at this from a business standpoint. You almost never take huge risks without a backup plan. Fen may attempt to resolve this and get things back to normal, but he will likely not do so unless he finds a viable alternative in case everything goes wrong.
Or he may go for broke and try anyway. Who knows. Either way, he is likely waiting for things to cool a bit before trying anything, which is a smart move.
Personally, though I ain't betting too much on it, I'm still holding out a bit of hope.
Anyway, just my two cents on the matter.
