Who needs source code?
Many developers feel that the supplying source code is essential for licensed software components. There are other perspectives, including the possibility of it being an actual disadvantage. Even the definition of source code has some vagueness.
Summary
Colin Walls examines the assumptions around supplying source code for licensed software components and argues that providing source is not always necessary — and can sometimes be a liability. Readers will learn how to weigh license obligations, maintenance costs, IP risk, and practical alternatives for embedded and productized software.
Key Takeaways
- Evaluate when source distribution is legally required versus when binaries or minimal artifacts suffice for product support.
- Balance compliance and IP protection by understanding obligations under GPL/LGPL and permissive licenses.
- Require reproducible-build artifacts, SBOMs, and build instructions from suppliers to enable long-term maintenance without full source disclosure.
- Plan for secure update mechanisms and supplier traceability to reduce supply-chain and maintenance risks.
