@ocdtrekkie @bagder This is just one case and might be outdated, but the mpv developer(s) rants more about macos than windows. Mpv which the original root fork was written for linux. https://github.com/mpv-player/mpv/wiki/FAQ
I wonder how much code is actually shared between platforms by common open source projects and which platform is hardest to develop for with the most hacks. Windows is hardest for curl, but it’d be interesting to know the rest.
