Understanding Open-Source Software Licensing

March 13th, 2025September 30th, 2025Richard KempNo CommentsReading duration: 2 min

Open-source software (OSS) is now ubiquitous across industries, providing organisations with cost-effective and scalable solutions. However, the use of OSS carries legal and compliance considerations, particularly regarding licensing structures and intellectual property (IP) rights.

The Open-Source vs. Proprietary Model

Software development models have traditionally followed either a proprietary (“cathedral”) approach, where source code is closely guarded, or an open-source (“bazaar”) approach, where code is freely available. OSS operates under licensing frameworks that dictate how software can be used, modified, and distributed.

Key Licensing Considerations

Open-source licences fall into two main categories:

  • Copyleft Licences (e.g., GPL, LGPL): These require derivative works to be released under the same licence, potentially impacting proprietary software.
  • Permissive Licences (e.g., Apache 2.0, MIT): These allow for broader commercial use without stringent obligations.

Legal teams must ensure compliance with OSS licensing terms to avoid inadvertent IP infringements or unexpected obligations.

Best Practices for OSS Management

To mitigate risks, organisations should implement OSS governance frameworks that include clear policies on usage, documentation, and compliance audits.
