I am leaving for a few days in a bit, but while I am shocked - this was to be expected. My guess is that his Doughnut project (hiding the incest) didn't do much good for his reputation either and possibly made him target #1 to set an example.
The best thing he can do is the following: cut all ties between DMD <=> Patreon and put the focus on a new, simple - very simple game. Promote the dummy game, and use it to rebuild his reputation with Patreon. While doing that - inform ALL current paying Patreons that root for his cause, using an e-mail service outside of Patreon - that they do not have to worry about DMD. As long as they keep on supporting, he will keep on developing DMG and send it to those that do. He already has everyone's emails and has a site running. He doesn't need more than that - just need to set boundaries.
As long as he is smart enough not to affiliate DMD with Patreon - he should be good. He shouldn't expect more pay though..
Sucks that we have to wait, but now he has been set free we should be able to get some KICKASS updates.
