I said commercial OS market to distinguish proprietary desktop operating systems (Windows and macOS) from Linux, the BSDs, MINIX, Haiku, Plan 9, OpenSolaris, FreeDOS, and other alternative operating systems. Windows and macOS is a duopoly, much like how US politics is functionally a two-party system. The existence of the Greens, Libertarians, and independent candidates don’t take away the fact that the Democrats and Republicans utterly dominate American politics to the point that third parties and independent candidates face major hurdles campaigning. Likewise, the existence of Linux doesn’t take away the fact that Windows and macOS combined dominate desktop computing.
Sometimes one needs proprietary software packages that only work on Windows or macOS. Granted, the situation in 2024 isn’t as bad as it was in the 2000s thanks to the evolution of Web apps as an alternative to desktop applications. Still, some people rely on heavy-duty desktop apps that rely on Windows- or Mac-only APIs. The GIMP and Inkscape may not fully replace Adobe Photoshop and Illustrator. FOSS diagramming tools, last I checked, aren’t at the level of proprietary tools that are unavailable for Linux like Microsoft Visio and OmniGraffle. Some people need functionality in Microsoft Office that is unavailable in LibreOffice.
