As a defender, I can only speak for myself. But from my perspective, and this is also sort of a general sense I get from others, I think the central point that is overlooked here is that all of your points may well be true; but I just don't care. It's a porn game. I'm not going to invest any time or effort into giving a single hot shit about how the developer manages the project. He has no obligation, imo, to deliver anything. Patronage is voluntary, it's not Kickstarter where you're funding a specific target amount for a specific goal. It's a tip jar for what has been delivered to date, not a future-focused budget pool. Good for him that his tip jar is so honkin' big.
