That's an opinion ungrounded in fact until the episode gets released and we can evaluate it.
As for whether other patrons are getting impatient, I'm not seeing anyone expressing any impatience, really. I don't spend much time reading comments on Patreon, so it's possible I'm not seeing them, but I expect the most common demonstration of impatience would be to discontinue being a patron, not leaving a complaint in the comments.
I mean, everyone here is free to express their opinions, of course. I understand impatience and am not insensitive to the argument that DPC is trying to ride this gravy train as long as possible. I think few people would act differently, but to some this may seem a form of "milking supporters." I played "Milfy City" and was as annoyed as everyone else when ICSTOR absconded, but I never contributed to his Patreon, so never posted any complaints or angry reactions. Why would I be angry? I'm not out anything. I'm disappointed that the game will (presumably) never be finished, but the time I spent on it was enjoyable.
So, when people who are not supporters complain about DPC, I find it ridiculous. Not only because they do not support the game financially, but because they are complaining based entirely on speculation.
