FOSS

FOSS stands for Free Open Source Software. If you see this used to describe some piece of software, usually it means that its allows the community to modify and use that piece of software for pretty much whatever. It also allows the community to push updates, often requiring official maintainers to give it the good ol' once over before they push it through. Its a wonderful system that allows the creators to be checked by the community for any malicious intent while allowing it to flourish with new features.
