Open source is a development methodology; free software is a social movement

Richard Stallman is a prominent figure in the world of technology and software development, known for his advocacy of free software and open source principles. He is often credited with popularizing the concept of free software and founding the Free Software Foundation, which promotes the use of software that respects users' freedom.

One of the key distinctions that Stallman has made in his work is the difference between open source as a development methodology and free software as a social movement. While the two concepts are closely related, they represent different approaches to the creation and distribution of software.

Open source is a development methodology that emphasizes collaboration, transparency, and community-driven innovation. It is based on the idea that making source code freely available can lead to better software through peer review and contributions from a diverse group of developers. Open source software is typically distributed under licenses that allow users to modify and redistribute the code, but may not always guarantee the same level of freedom and user control as free software licenses.

On the other hand, free software is a social movement that prioritizes users' freedom to run, study, modify, and distribute software. Stallman has argued that software should be considered free not just in terms of cost, but in terms of the freedoms it provides to users. Free software licenses, such as the GNU General Public License (GPL), are designed to ensure that users have the freedom to use, share, and improve the software they use.

Stallman's advocacy for free software has had a significant impact on the tech industry, inspiring a new generation of developers and organizations to prioritize user freedom and ethical considerations in their work. The Free Software Foundation's work has also helped to raise awareness about the importance of software freedom and the potential risks of proprietary software.
