What is the difference between free software and open source software?

Free software and open source software are often used interchangeably, but they have distinct philosophies and emphases. Free software, as defined by the Free Software Foundation, emphasizes the importance of user freedom. It promotes the idea that software should allow users to run, study, change, and share software freely. The focus is on the ethical and social implications of software use, emphasizing user autonomy and the right to control one's own computing. On the other hand, open source software primarily focuses on the availability of the source code and the collaborative process of developing software. The Open Source Initiative champions an approach that prioritizes transparency, community collaboration, and developmental benefits. While open source projects often share principles with free software, they do not necessarily emphasize the ethical aspects as strongly. In summary, both terms advocate for access to source code and user collaboration, but free software underscores user freedom and ethical considerations, while open source highlights practical development processes and benefits.
