Hundreds (thousands?) of API calls in both Desktop iOS development are prefaced NS_ ... that is NeXTSTEP
Before the OpenStep revamp, the class prefix used in NeXTSTEP was "NX". I think there are still some lingering NX* classes/functions you might see in AppKit stack traces.
NeXTStep 3.0 used the NS namespace; 2.0 and earlier was NX.
Merriam Webster actually lists both meanings (small fact and non-fact). https://www.merriam-webster.com/dictionary/factoid
Both Jobs and Gassée were both forced out by Sculley who alot of people credit with driving Apple toward the mediocrity that defined it in the mid 90s.
The other big factor at the time was the fact that BeOS ran on PowerPC, and NeXTSTEP did not. NeXT had done some work to produce their own hardware with dual 601s, but never shipped it and abandoned that work to focus on the IBM PC hardware. This meant that the first few years of the Apple/NeXT merger were spent just getting NeXTSTEP running on PowerPC.
The biggest buzz of the time was that even though Steve's return to Apple had killed the growing Mac clone industry, maybe Rhapsody would run on x86 hardware. There were rumors all over that they would make this happen, although they were many years too early, as Apple wouldn't make that switch until 2005.
NeXT was an actual operating system that people used. You could run word processing apps from which you could print and email. There was a fully fledged development platform with real developers building real third party apps. BeOS was more like a giant tech demo.
If we focus on just the technologies choosing BeOS would have meant at least a few years more engineering effort. And you still wouldn't have been able to replicate the ground breaking nature of OSX in the short time frame required.
I suspect both financially and in consumer mind share they would have never recovered from selecting BeOS.
