I agree with your implication that the person you replied to doesn't appear to understand how Patreon works, its mission, or specifically the "contract" patrons agree to when subscribing to Dark Cookie.
And for 80% of the adult game developers - it is hobby, a side-gig, or a passion project. The average Patreon adult game developer pulls in about $100 USD per month. For some, they hope to transition it into a full-time gig. Still, only 10% bring in more than $1000 USD after at least 3 years of seeking funding on the Patreon platform.
But for clarity's sake - for Dark Cookie, his small business grosses about $60,000 USD per month and this is not only his occupation, but he also contracts several others to code, pose, write, etc while he draws the art and manages the project how he decides in running his own business.
