DMD was simply removed from patreon, and besides, it was the rare case when, on the wave of gigantic popularity, it managed to get good sales on subscribestar and on the author's official website. Even so, it's not certain that DMD would have been filled with so much controversial (and patreon-banned) content if it weren't for the success of another game that came out a little later (Melody), the proceeds from the sale of which (via patreon) largely allowed DMD's creator to continue working on it.
But there are other ways to circumvent censorship, more risky (at least as long as such a game is sold through patreon) but quite workable. I've already given examples of such games here, where developers have successfully implemented controversial content without leaving patreon or being banned there. Of course, it's better for the DM to take no chances, because everyone wants to see how Monica's story ends, not bite their elbows over the game being blocked. But anyway, I agree about hope.
