I’m rather “meh” about the whole thing.
Desktop operating systems are commodity, and there’s not much money in them. Even Microsoft doesn’t make much from Windows outside of the enterprise use case. You can download it for free if you don’t care about chaging your own wallpaper.
What little money there is for desktop operating systems is in App Stores. Linux has a bajillion of them, they all suck.
The few successful, desktop focused Linux distros also make hardware, which this announcement didn’t indicate was coming.
Finally, the rolling nature of Manjaro and the… simplicity… of pacman do not lend well to enterprise use cases.
I wish them well, but I’m skeptical this will matter, let alone be a good thing.
