They haven't done it because it doesn't bring any benefits to the greedy corps, and apple is the worst offender with their dumbed down, shackled os
So how is MacOS - a real certified Unix OS “dumbed down”?

A storm of security issues is closing in on the Android version of Fortnite. And it isn't likely to pass anytime soon.
Developer Epic Games just fixed a security flaw with Fortnite's installer for Android devices, but researchers are expecting a flurry of problems for the online game as it gets more popular on Android.
That's because Fortnite isn't available through Google's Play Store. Epic instead chose an unorthodox -- and more dangerous -- route for the game's fans. Rather than download it through the official Google app store, players need to download the game and "sideload" the app on their Android devices instead.
Apple is going down this route with code signing and granular permissions with Macintosh applications that don’t have to be part of the Mac App Store and there is still whining from geeks that this is leading to a walled garden, even though there are approved ways to work around it.
It's the same with Electron apps by the way, those wouldn't exist if operating systems would come with cross-platform UI frameworks that are actually better than the unholy mix of HTML+CSS+JS. But Microsoft, Apple etc... had decades to get their act together without delivering.
One of the problems with Electron is that it’s the same interface everywhere. I don’t want the same interface on a Mac that I have on Windows.
