As far as I know they largely based this on Cocotron[1], without giving credit. And of course it wasn't so much "giving up" (which sorta implies it was the difficulty of the task), but more "losing interest", because they discontinued Windows Phone, where they were behind Apple's iOS in terms of market share. In that context, getting iOS apps on their system is economically interesting. On desktop, Windows is way ahead of macOS in terms of market share, so there isn't much of a point.
