In order to engage the subject matter of the article, I'm going to pin down the definition of Unix as some POSIX-compatible server OS with some Unix shell running on top of it. I think this encompasses most of the worlds' server infrastructure that runs some variant of Linux. The article implies that Unix is superior to Windows because people use it for real work as opposed to just diddling about in some graphical application. This is a massive misrepresentation. While bare-bones Unix is well designed for simple scenarios, like running a server with ethernet and disk access and static hardware and yields itself to implementing Unix-style shells with fork() and pipes, it is not enough OS for a proper desktop environment. In other cases, it is too much OS. I remember designing and writing software for an embedded voice recording system for railway dispatchers, which had things like remote ethernet configuration, writing the recordings to a FAT32-based SD card on a 60MHzish uC with 128k flash and 64k RAM. It had no OS, everything was running on the bare metal. Going back to my previous example, if one images running a single web server process in a VM container, one could just design some hypothetical architecture, that allows you to do this with all the low-level stuff is put into a small statically linked library, and the app is the OS itself. Imagine plugging in a USB bluetooth dongle to play some music on your headphones. In response the OS needs to load some drivers, start the bluetooth service, tell the audio service to output audio to your headphones etc. Windows can do this out of the box. Linux can be made to do this, either with a massive proprietary Android task or systemd/pulseaudio/bluez/whatever if you're in the open-source world. At this point Linux can be hardly called a Hole-Hawg. The perceived superiority of Unix also leads to the false conclusion about Android/macOS/Desktop Linux being superior to Windows (or any other hypotethical fully fledged OS). In order to handle the massive complexity imposed by the complex scenarios, the systems themselves have to be complex as well, with varying success. I'm willing to bet, most of the code that allows me to write this comment on macOS on a HW accelerated GUI using a bluetooth keyboard is part of the Apple-monolith and has nothing to do with Unix/POSIX. The same applies to the other "Unixes" I mentioned earlier.
