First, true. However what is the scam? No one is promised anything for their subscription except for what is stated in the tier benefits on Patreon. Which DC and the Dev team do adhere to. The game is not a tier benefit. A finished game is not a tier benefit. At no time does DC say if he doesn't get $$$$ that he won't be able to work anymore.
Second, true and false. True that this game has always been free and will be free for the foreseeable future. False on it always intended on being finished. In fact, DC has stayed many times, as early as 2017 in interviews, etc that:
And has mentioned as recently as September that he could easily see 100, 200, even 300 NPCs for Anon to interact with.
