Jesus christ, he should have stuck to SFM rather than switch to Blender. Make up for whats lacking in "GRAFIX" for niche content. He had some Beast/BLACKED/Shota NTR shit going on that no one but General_Butch is putting out. He fucked up that he didn't foster that shit, I mean BLACKED cgi content (Disregarding your own personal feelings towards it) is a money maker. He'd have enough patrons to not actually work. People are still making good shit with SFM, just master it. 26Region is making monsters hentai in SFM, I don't see others making that shit in Blender. It's unfortunate.
To add, I did support it him in patreon from the Lara-Croft shota pirate to the Super Mutant length film; then called it quits since he failed to deliver on the latter. I didn't know he had a day job, it was a mistake for him trying to learn Blender while outputting content using Blender. It's sad to see him fizzle out; I was hoping for my "My Neighbors Wife"
Beast/Black/Shota was more niche back when he started (haven't seen someone else do Black Shota, except Kaiba), and sfm was the norm. But things changed: nowadays those are just more options made by a decent ammount of creators, be it in video or WEG form (I do think WEGs apply).
So artists try to change their content a little, either because they think that will keep support/make more of it or just because they wanna try something new. Some change Software, some try and make things that others don't, some try to put out more content and others try a quality over quantity approach.
Sum didn't fare well with the changes he made IMO, but the support in his patreon kept steady, so he kept going. Now that Patreon finally fucked him over (as it has been doing many others from what I've seen), he's trying to stay afloat by communicating more and finishing his big Blender project. If that works, I don't think he will fizzle out at all, so I hope it does work.
