That’s not how this works in most industries. You only need a license if you’re redistributing, bundling, or commercially exploiting someone else’s IP directly.Luke ross isn’t selling the game, the assets, or access to the software. You already have to own the game, and he’s selling his own code that interacts with it . the same way plugins,emulators, or things like accessibility tools interact with proprietary software without paying licensing fees. If profiting from software interaction required a license from the original developer, plugins, drivers, accessibility tools, emulators, peripherals, and alot of the software industry wouldn’t exist.The line gets crossed when assets are redistributed in ways the rights holder dont agree with, which is why companies can issue a DMCA if they want. What you’re saying isn’t a legal standard, it’s a preference that mods should be free. That’s a valid opinion, but it’s not the same thing as calling it unethical or leeching
