I'm not hating on Carbon or anyone else either. All I ask is that devs just play it straight. I couldn't do what devs do, so if it takes a year or more to produce a VN, so be it. Clearly, some have been incredibly successful and make a living from it, others less so and/or just do it for the love of it.
There are definitely some milkers on here/Patreon/Subscribestar (no names mentioned) and the mugs are the ones who keep paying in the vain hope something new will come along. I'm lucky enough I don't even notice the payments that go out each month for Patreon support and if nothing is forthcoming, I'll eventually say fuck it and cancel. But I don't think its unreasonable for devs to be open and honest. Personally, Id rather have my integrity than a few extra $$ a month by stringing people along who enjoy your work.
