It's open source though and they plan on adding Linux/Windows support in the future

Side note: Rust is the only of the three to have an ML-style type system, which is generally agreed upon as one of the most theoretically sound foundations. Also the point is that Rust does it precisely without requiring dynamic allocation, as opposed to Go, for example.

A nice example of this is Ardour: A DAW that's free in the sense that the source code is GPL, but the prebuilt official binaries have to be paid for.

How so? It's a polished Unix desktop that runs most open-source and a bunch of proprietary apps, including Final Cut and Logic. It's natively POSIX and has a proper shell.

Swift does, though using the dollar sign rather than underscores

That article tells you how to set up syntax highlighting and run the command-line compiler by hand, not really comparable to IntelliJ... The article feels like a generic SEO post

Just wanted to point that rust-analyzer is the fantastic language server that powers the language support, and it runs in a lot of editors (VS Code, Emacs, Neovim, ...)

This is all fun and games until you try moving a backup to a file system that's case-insensitive

In principle you can, the Mach-O format is openly documented and implemented in the major compilers. The issue is that you need a sysroot (aka SDK) of the frameworks and headers for your target OS, which in Apple's case are proprietary and cannot be redistributed legally (you could probably rip them out of a macOS installation yourself though). For iOS apps you'd also need to sign the binaries and install the app to the device which is non-trivial to impossible to do on other platforms.
