The StackOverflow 2019 survey suggests 47% of developers are on Windows (https://insights.stackoverflow.com/survey/2019#technology-_-...). This is a big chunk of developers you can't reach well, if you are limited to Linux and/or macOS. Windows devs might desire to have Crystal because they want to build native apps, but the reality is many people use the OS for other reasons that are beyond their control.

I don't find it surprising to see this question in a discussion involving a language related to Ruby. It's a bit sad it still comes up, but there is overwhelming demand for better Windows support of this and any other good or promising software running on Linux or macOS.

Historically, Python has had reasonable Windows support. It got to a point where it was OK and stopped improving. In recent years there has been more attention and improvements. This investment has meant that the language is reasonably viable for a lot of tasks on Windows. This doesn't mean that there hasn't been an influx of folks at points with little knowledge or care for Windows, but lots of packages work reasonably well.

Ruby is a different story. Rails was the big growth driver and there was a narrow focus. The pattern emerged of dev on macOS and deployment on Linux. I personally credit the tropes about only seeing Macs at dev conferences in a big way to Rails. The result is that it's infeasible to use Windows directly and you are best to go with a VM, or now WSL 2.0. It didn't have to be this way when a big chunk of developers are Windows. Rails could have taken an even bigger chunk of the market if Ruby had better Windows support.

Strategically, Crystal and other languages that want real adoption and the things that go with that (more recognition, more libraries, more real world use, more contributors, etc.) need to work out a good plan for Windows support.
