Product Overview
The Free Software Foundation (FSF) is the core organization of the free software movement, founded by Richard Stallman in 1985. FSF advocates for four essential freedoms for software users and maintains the GNU General Public License (GPL) series. Although OpenClaw has opted for the more permissive MIT License, FSF's free software philosophy remains an important context for understanding the open-source ecosystem.
Four Essential Freedoms
| Freedom Number | Content | Description |
|---|
| Freedom 0 | Freedom to Run | The freedom to run the program for any purpose |
| Freedom 1 | Freedom to Study | The freedom to study how the program works and modify it |
| Freedom 2 | Freedom to Distribute | The freedom to redistribute copies of the program |
| Freedom 3 | Freedom to Improve | The freedom to improve the program and release improved versions |
GPL License Family
Main Licenses
| License | Characteristics |
|---|
| GPL v2 | Classic Copyleft License |
| GPL v3 | Adds patent and DRM protection |
| LGPL | Weak Copyleft, suitable for libraries |
| AGPL | Requires open source for network services |
Comparison with MIT License
| Dimension | GPL | MIT |
|---|
| Philosophical Basis | Ethics and Freedom | Pragmatism |
| Derivative Works | Must be open source | Can be closed source |
| Commercial Use | Allowed but with restrictions | Completely free |
| Patent Protection | Included in GPLv3 | None |
| Viral Nature | Yes (Copyleft) | No |
Reference Significance for OpenClaw
Reasons OpenClaw Chose MIT Over GPL
- Business-Friendly - MIT allows companies to build closed-source commercial products based on OpenClaw
- Ecosystem Expansion - Permissive license lowers the barrier for third-party integration
- Community Growth - Fewer legal restrictions attract more contributors
- Fork Freedom - Allows language forks (e.g., ZeroClaw) to choose their own license
FSF's AI Stance
- The free software movement focuses on user freedom in AI systems
- Challenges in defining the "source code" of AI models
- Issues with the free sharing of training data
- Importance of user control in AI agents (e.g., OpenClaw)
