Given this experience, I just don't get how cross-platform UI-frameworks are somehow a bigger PITA than pulling in and involving a whole other set of technologies.
Brings up a third point when talking about development. Microsoft is providing a posix compatible dev environment under Win10. The threat that poses is completely unappreciated.
But all of that is really beside the point. Saying the "community" needs to fix it means they won't put time or effort into doing it themselves, which by extension means the integration will most likely never be as good as what they have prioritised. This will relegate their "cross-platform" solution to the realm of all the other frameworks: Bad.
