I remember Silverlight being advertised as a cross-platform solution (in small print: works on all supported Microsoft(R) Windows™ platforms!). To this day there are things written for Electron which are „cross-platform” in the sense that Windows and macOS are supported, but none of Linux or *BSD.
Thus I have some warm fuzzies when something new is cross-platform, but not on Windows. (But hey I heard WSL supports Wayland?) Even more warm fuzzies if Windows users come to whine about availability. Happy to have lived to see this turning of tables come.
