I wasn't responding to all of the comments. I was responding to you.

That was totally possible before. VM passthrough works fine, (even "natively" with VMWare's software), and mingw is perfectly capable of native cross-compilation. WSL is neat, but it's not any more advanced than what Chromebooks have had for years. Hell, it's barely more impressive than MacOS' POSIX compliance.

You can cross-compile MacOS and Windows apps on Linux just fine (done it many times before). Of course, you can also target webdev and mobile devices, as well as Docker, Kubernetes and other service-oriented software. But you're right, writing Fart Simulator for iOS is where all the real money is. I'll defer to your opinion rather than the thousands of people on this very site making money off headless Linux servers.

Sure, if they don't want to write system services, self-hosted websites, self-custody backends, databases, Kubernetes clusters, CI/CD pipelines, Docker containers or test DevOps services locally, then that is all they need to know about Linux. They should focus on the actual breadwinners, like getting their 70% from the App Store.
