This article is full of nonsense. The Linux desktop push isn't failing because it has experiences and apps that are similar to Windows and macOS. Being able to run Windows apps on Linux is a benefit, not a failure. As for religious wars over init systems, desktop environments and package managers, competition is making the options stronger, not weaker. Competition is a reason why package management on Linux is far better than equivalents on Windows and macOS.
The main reason for Linux not taking off on the desktop is because most users don't care about what OS they run, they just want a computer that works. If the PC they buy comes with Windows out of the box, they're going to stick with that. Until you get manufacturers shipping PCs with Linux as the default OS, you're mainly going to see desktop Linux as an enthusiast-only option. It's no accident that one of the devices helping to spread Linux (the Steam Deck) comes with Linux as the default option.
