Umm, I think you are slightly wrong with your facts. It is true that SSR7 got hit with a DMCA over the title of the game. I can't remember what it was now, but instead of Unlimited, it was an actual DC title. SSR7 & Smokeshank ponied up for a lawyer and they just had to change the title as the art was all new and not assets from DC. I was a patron until late last year and there is constant talk of SU on their Patreon - updates, news of new releases, pictures of upcoming events, etc. I personally am not sure if Patreon actually shut down their site or if was just DC lawyers coming after the creators, as I was not a patron then.
Now, BB & DS is a totally different fruit. His problem wasn't copyright infringement, but breaking Patreon's rules. No incest. BB was rightfully concerned with losing his financial stream and maybe he saw how Patreon was cracking down on other developers and he didn't want to risk it.
Now with all that said, I do agree. I don't think DS was interested in this project anymore. Whether his lack of drive came from the fact his game was being cracked and pirated, or he had to wrap up the Eric angle faster than he had planned because of the backlash, or he lost focus and didn't know how to wrap up the game, or he just lost all ambition on the project. Maybe it's a combination of these and/or other factors. In my opinion it is unfortunate. I don't think the game itself is spectacular, but DS knows what he is doing when it comes to rendering images!
