Timing is a given… the whole point is now there is a duopoly it’s impossible to compete.
Windows Phone OS was excellent, smooth, efficient and relatively intuitive with flagship models competing with Google and Apple.
The problem was getting apps created for the App Store with the lowest market share. The phone sector was losing money, it did that for years with no great improvement in market share. The call was made entirely because Microsoft can’t have a red mark on their balance sheet for that long without investors getting annoyed.
It was the money.

I wouldn’t call $7.6 billion half-assed, but maybe that’s just me.
