Why we need it?

10 of 27

  • Freedom & Control: No vendor lock-in, transparency.

​

  • Security & Privacy: Open code means no hidden surveillance.

​

  • Cost Efficiency: Free to use, widely adopted in enterprises.

​

  • Collaboration & Innovation: Enables faster development (Google, Red Hat, IBM all invest in FOSS).

​

  • Real-World Impact: Govt. use (DigiLocker, Aadhaar backend uses open-source tech).

Industry Support: Tech giants like Google support FOSS through funding, Google Summer of Code (GSoC), and initiatives like Season of KDE (SoK) to promote open-source contributions.

What are FOSS Licenses?

FOSS licenses define how software can be used, modified, and shared. They ensure freedom while setting rules for usage.

License

Key Features

Example Projects

GPL (GNU General Public License)

Requires derivative works to also be open-source (Copyleft).

Linux, GCC, WordPress

MIT License

Permissive; allows commercial and open-source use with minimal restrictions.

React.js, Node.js, Expat

Apache License 2.0

Similar to MIT but includes a patent clause for added protection.

TensorFlow, Kubernetes, Android

BSD License

Permissive like MIT, but used in academia and industry.

OpenBSD, FreeBSD, PostgreSQL

Major Open-Source Licenses

  • GPL ensures contributions remain open-source (e.g., Linux cannot be turned proprietary).
  • MIT/Apache allow commercial companies to use open-source software while keeping their changes proprietary.
  • Some companies exploit open-source without giving back (e.g., Microsoft Copilot controversy).

Why Licensing Matters?

The Copilot Controversy

GitHub Copilot, developed by Microsoft, uses AI trained on publicly available open-source code.

​

Developers argue this violates copyleft licenses (like GPL), as Copilot generates proprietary code without crediting original projects.
