I'm fine with this when it's some freestanding native-compiled C+DirectX application. But it really irritates me when the Windows version is, after all, just a bunch of scripts loaded into a scripting runtime (think e.g. Love2D, or RenPy); but then the first-party macOS/Linux downloads turn out to be WINE wrappers wrapping the Windows version of the scripting runtime, rather than using the macOS/Linux versions of the scripting runtime. I get that people don't always have multiplatform development setups; and that there are easy-to-use tools that "wrap" a Windows application into macOS/Linux versions. But these runtimes usually also have cross-"compilation" options that are just as easy to use!
