Look, I get that it's all the rage to bash on Patreon for their rules, but they are seriously not at fault here. Nverjos never once indicated that he was chafing under their restrictions, at least not that I ever saw. He had his reasons for leaving the project, we can speculate, but may never really know for sure.
I do think it's pretty scummy of him that he's still taking people's money, though. Others in this thread have indicated they've seen activity from him in other venues, so he's alive and functional enough to make posts in places, but not to turn off taking payments for a game he's not working on anymore? That's pretty douchey.
