Bit off topic, but when it comes to selling games, Copyrighted music is an absolute no no, as its the easiest to spot for a simple program. This is why youtube creators for example, are always complaining about being copyright striked, because the simple program that flags the video just seeks out the music no matter if its the whole song or 5 seconds.
Asset flips however are kind of a weird no man's land. Like, you see all these steam games being released by solo and small dev teams that are almost entirely "stolen assets" but they can get away with it because whoever made the assets originally and posted them online, "technically" released them with the knowledge that they could be used for whatever. Usually these assets are released for purchase, but all it takes is someone else posting the models online and there is nothing the original creator can do about stopping people downloading. Sure they can ask for the models to be taken down but they will have already been downloaded a thousand times before anything happens.
I'm just dumbing it down for simplicity sake, but this is why people can steal say, artwork, models, code, or even videos, and claim them as their own because it's harder to prove to a computer that they didn't make it, or if they change one thing about the work to make it "original". The simple program that steam, for example, uses, just looks for certain content, say certain NSFW features, and flags those for a human to take a closer look at before the game is approved, but not the models in the game.
It always comes down to the fans to point out what has been stolen or asset flipped, as companies like youtube or in this case patreon don't care/have the time to go and look for themselves. This in turn basically leaves it all down to the original creator of the assets to do something about the "theft", if they can even prove it is theft, not to mention the sheer amount of time it takes to process everything and what the outcome is (and if it will even be worth it).
I promise you, if the creator if the models tried to shut down this game or anything, they wouldn't see any money from it, and would earn the ire of the fans of the game for stopping the production.
So basically, the end result is the platform doesn't care about asset flips, the original creators of said assets don't care (to an extent), and the dev team of the game doesn't care they're using the assets (saves them creating their own and cuts dev time).
So, in this case, everyone just collectively shrugs and gets back to fapping.
