Why Linux Desktop Systems Are Favored by Governments and Their History

Recent discussions on Zhihu have sparked interest in why state-owned enterprises and government computers are being replaced with Linux environments, despite Linux holding less than 5% of the global desktop OS market share.

While many cite geopolitical "bottleneck" reasons, this article examines Linux purely from a technical perspective, highlighting its enduring appeal.

Linux began in September 1991 when Linus Torvalds, motivated by personal interest, released the first 10,000‑line kernel. The kernel alone is not a complete OS; various organizations and vendors combine it with software, documentation, and management tools to create full Linux distributions.

Distributions have driven Linux’s adoption, with two main categories: commercial (e.g., Red Hat) and community‑driven (e.g., Debian). In China, four distributions dominate:

Red Hat Linux – the most widely used, offering RHEL (paid) and CentOS (free) alongside Fedora.

Ubuntu Linux – derived from Debian, user‑friendly, hardware‑compatible, and entirely free.

SUSE Linux – originally based on Slackware, now maintained by the openSUSE community.

Gentoo Linux – source‑based, highly customizable, and fast once compiled.

Governments favor Linux for several reasons:

Abundant free software (e.g., Apache, Samba, PHP, MySQL) reduces deployment costs.

Excellent portability and flexibility allow Linux to run on virtually any CPU architecture, from USB sticks to embedded devices.

Strong stability and security stem from open‑source transparency and a smaller attack surface compared to Windows.

Comprehensive support for network protocols and programming languages (C, TCP/IP, PHP, Java, C++) makes it ideal for development.

Examples include Munich’s 2004 switch to Linux (later reverted), Korea’s 2019 mandate to replace Windows 7 with Linux, and Poland’s collaborations with Linux Polska. Despite these advantages, Linux’s desktop market share remains limited, and broader adoption will require treating it as a mainstream consumer product.

In summary, Linux’s open‑source nature, mature ecosystem, portability, stability, security, and protocol support make it a compelling choice for governments, even though achieving significant global desktop market growth remains challenging.
