Eh? Welcome to the 21st century. Windows is no longer the dominant platform, thankfully.
I actually think that’s one of the things that is holding this project back. Fewer and fewer people have windows these days - Macs, phones and tablets are the order of the day. apm_planner2 sadly seems to have been put to bed, and qgroundcontrol is a really nice cross platform GCS but it still needs work particularly with ardupilot. I keep a windows VM around literally for the sole purpose of running Mission Planner when I absolutely have to. Particularly as this project is more likely to attract technically competent/interested people, who are much more likely to be using Mac or Linux.
