I didn't know bundling app for the most popular OS is that hard.
What I meant was there are so many problems with Windows that the team cannot do it quickly (they post about it before: https://zed.dev/blog/windows-progress-report).
Just surprised, as I thought building GUI app on Windows must be easy right, as must be libs/frameworks already available to support that? It's just not.
It obviously varies a lot by the preferred languages, but Windows is still at the top, on average.
Turns out there are plenty of other jobs as programmers.
