I guess the "Why not Linux?" part of our FAQ is as much of an excuse as one can make, besides pure curiosity of course: https://www.haiku-os.org/about/faq#why-not-linux https://www.haiku-os.org/about/faq#why-not-linux > Linux-based distributions stack up software – the Linux kernel, the X Window System, and various DEs with disparate toolkits such as GTK+ and Qt – that do not necessarily share the same guidelines and/or goals. This lack of consistency and overall vision manifests itself in increased complexity, insufficient integration, and inefficient solutions, making the use of your computer more complicated than it should actually be. > Instead, Haiku has a single focus on personal computing and is driven by a unified vision for the whole OS. That, we believe, enables Haiku to provide a leaner, cleaner and more efficient system capable of providing a better user experience that is simple and uniform throughout.
