Overview
Open source software has become foundational to modern software development. Most commercial applications contain significant open source components—libraries, frameworks, tools, and infrastructure. This reliance creates legal obligations that vary dramatically based on which open source licenses apply. The difference between permissive licenses (MIT, BSD) and copyleft licenses (GPL, AGPL) can determine whether proprietary modifications are permissible.
Open source compliance requires systematic processes: identifying open source components in codebases; understanding the obligations each license imposes; ensuring compliance with notice, attribution, and source code requirements; and documenting compliance for due diligence purposes. Failure to comply can result in forced disclosure of proprietary code, injunctive relief, and reputational damage.
Beyond compliance, open source presents strategic opportunities. Contributing to open source projects can build reputation, influence standards, and access community innovation. Releasing software as open source can accelerate adoption and create ecosystem effects. Commercial open source business models—open core, dual licensing, support and services—can generate revenue while maintaining community engagement. Strategic open source decisions require integrating legal, technical, and business perspectives.
Key Considerations
License Identification
Systematic processes to identify all open source components and their applicable licenses.
License Categorization
Understanding permissive vs. copyleft licenses and their different obligation profiles.
Compliance Requirements
Attribution notices, source code availability, and modification disclosure obligations.
Contribution Policies
Employee contribution guidelines, CLAs/DCOs, and IP assignment for contributions.
Commercial Integration
Strategies for combining open source with proprietary software while maintaining compliance.
Due Diligence
Open source audits for M&A and investment transactions.
Applying the TCL Framework
Technical
- Open source compliance begins with technical identification. Software composition analysis (SCA) tools scan codebases to identify open source components and their licenses. Understanding how components are linked—static vs. dynamic, library vs. service—affects license obligation analysis. Technical architecture decisions (modularization, API boundaries) can enable proprietary development while using copyleft components. Build and deployment processes must support compliance (license notices, source code archives).
Commercial
- Open source creates commercial value while imposing obligations. Commercial decisions include: Which open source components provide more value than their compliance costs? How should proprietary products be structured to enable open source use? Should products be released as open source to accelerate adoption? What business models (support, enterprise features, hosting) can monetize open source? Commercial open source strategies require balancing community engagement against revenue generation.
Legal
- Open source licenses are copyright licenses granting permission to use, modify, and distribute software subject to conditions. Permissive licenses (MIT, BSD, Apache 2.0) require mainly attribution. Copyleft licenses (GPL, LGPL, AGPL) require source code availability for derivative works or, for AGPL, network use. License compatibility affects combining differently licensed code. Contribution agreements (CLAs, DCOs) govern contributions to projects. Indian contract and copyright law applies to open source in India, though licenses are typically drafted under US/international frameworks.
"Open source is not free beer—it is free speech. The freedom comes with responsibilities. Organizations that treat open source as merely "free stuff" eventually discover that the obligations they ignored have consequences."
Common Pitfalls
Unknown Components
Not knowing what open source is in the codebase makes compliance impossible. Automated scanning is essential.
License Misunderstanding
Treating GPL like MIT or assuming "free" means "no obligations" leads to compliance failures.
Attribution Omissions
Failing to include required notices, copyright statements, and license texts.
Contribution Confusion
Employees contributing to projects without clear IP assignment or employer authorization.
M&A Surprises
Discovering significant compliance issues during due diligence when remediation is costly or impossible.
Open Source Legal Framework
Open source licensing operates primarily through copyright law—licenses grant permissions that would otherwise require copyright holder consent. In India, the Copyright Act, 1957 provides the underlying framework. Open source licenses are contracts granting rights subject to conditions; Indian Contract Act principles apply to interpretation and enforcement. Key licenses include: MIT/BSD (permissive, minimal obligations), Apache 2.0 (permissive with patent grant), GPL family (copyleft requiring source availability), and AGPL (copyleft including network use). License proliferation has created compatibility challenges—OSI maintains the approved license list. The Open Source Definition provides principles underlying license approval. Courts globally have enforced GPL and other licenses through copyright claims.
Practical Guidance
- Implement software composition analysis to identify all open source components.
- Create a license policy categorizing licenses as approved, restricted, or prohibited.
- Establish review processes for introducing new open source dependencies.
- Maintain compliance documentation (SBOM, attribution files, source archives).
- Define contribution policies addressing employee open source activity.
- Conduct open source audits before significant transactions.
