This document discusses software freedom and proprietary software. It defines free and open source software as software that respects users' freedom to use, copy, study, modify, and redistribute the software freely. In contrast, proprietary software allows the copyright owner to control and restrict users' rights, typically only allowing execution under certain conditions. The document argues that free and open source software contributes to technological sovereignty by guaranteeing unrestricted access to knowledge, reducing espionage risks, and promoting autonomous economic development.
