That still doesn't justify the slow pace of the game's updates and content. Just because you now have a reliable source of income fans are willing to give you doesn't mean you can slack off, do jack all in the meantime, get into drama, or plan for a roadmap you certainly won't meet unless you change your priorities. If anything, that can harm your image, create speculation and doubt, hurt the source of income, and ruin your reputation if it's not controlled.
And yeah, I get it, giving people money to make pornographic content for you to jack off seems a bit silly, regular coomer behavior even, but on an artist's side, it's definitely worth an investment to have a Patreon open and give the people a chance to give something back. On the opposite perspective, it wouldn't be just the regular "thanks for the boner bro, have a buck," but moreso "hey, I like you as an artist/person, keep going!"
Now it may sound like I'm defending the dude, but I'm not. They're just milking it and slowing things down, what with drama and all. People just gotta know where their money's going, what's it being used for, and just being smarter on where they're spending it, otherwise the cycle keeps going and no one learns.
...heck, one could speculate he's taking advantage of a promising concept covered with competence and grabbing as much dough as he can for the suckers that don't know any better, but who knows?
