” Android and iOS users keep hoping that MS will develop their applications to also work with Android and/or iOS. That’s a mark of perceived and real superiority.”
Apple already has done it.

That’s a good link you provided about Office apps becoming top 10 in the iOS ecosystem.
Which goes straight to proving my point, that the Apple people and the Android people, want what Microsoft provides, which is superior to whatever apps might be provided by Apple or Google or others.
But, thanks for proving my point.
Stick with me; you’ll learn a lot more.
