Description

Ubuntu is a leading open-source operating system, offering a robust, privacy-focused and customisable alternative to Windows. It is developed by Canonical and a global community, emphasising user control, security and sustainability. Ubuntu is free from forced data collection, ads and proprietary restrictions, making it a strong choice for those seeking digital autonomy and environmental responsibility.

Ubuntu's commitment to long-term support (LTS) versions ensures stability and reduces e-waste by extending the lifespan of hardware. Its modular design allows for easy customization and repair and its strong focus on security—including regular updates and a proactive approach to vulnerability management—further enhances its sustainability.

While Ubuntu has faced some controversies, such as a recent decision to prioritise GPU performance over certain security mitigations for Intel hardware, these are generally well-documented and allow users to make informed choices about their configurations.
