You can be critical of time-frames or content, sure, but just not understanding the concept of a Patreon is pretty stupid. You're funding the production of a product. You are aware of this fact when you subscribe to a Patreon. If you're dissatisfied with the product's production, then you no longer support them. It is an *incredibly* simple concept to understand.
Not my money, and not yours either, so I have no clue why you're complaining. I've already made my disapproval of the way the development was handled in terms of maintain open communication with the public (which should be considered for a production of any size), but just literally having a Patreon isn't an issue for anyone who actually understands what a Patreon is.
