"I'm genuinely sick of ppl abusing others on Patreon" ... who says they're being abused? They're adults who subscribed to a service. They're responsible for their own money. It's not your duty to be offended for other people. Keep your nose in your own business. It would be a scam if he did nothing at all and cheated people out of money. When you sponsor these games, you know they might not finish. You know they might drag on. Let's add to this a little, what if he completely finished the story with an ending everyone liked? Would be trying to be some sort of super hero by convincing people to stop paying him now that it's over? You call it a scam, but it isn't. They all signed up knowing how these things work. If they don't stop the subscription, that's on them. You also don't get to decide for everyone else what they do or do not deserve to pay for or when that property should be finished. If YOU don't like it, then YOU go somewhere else. Running your mouth about it, and trying to be some kind of Social Justice Warrior is you enforcing your opinion on everyone else.
Here's a better idea. Stop watching this thread. Stop playing this game. Stop complaining about this dev. Go about your own life and leave things alone that aren't your business, other than to be a nosy Karen about it.
By the way ... being "an old sub and an active member of the Patreon community and game development community" doesn't give you any kind of badges or authority. It just means you've posted on things and seen games. That doesn't make your opinion any more valid or important than the guy who posts two under you. It means that you've been around here for a while. So what? So have I. He isn't cheating anyone. YOU think he is, so he must be. But you're giving yourself way too much importance. Live your life, stop trying to live everyone else's too.
