Open Core' and 'Open Washing

Understanding the nuances of open source software is important for small businesses seeking cost-effective, flexible, and transparent solutions. However, two practices-open core and open washing-can blur the lines between true open source and proprietary models, potentially leading to confusion, vendor lock-in, and unmet expectations. Here, we explore these concepts in depth and provide guidance on how small businesses can identify and avoid their pitfalls.

Open Core Model Explained

The open core model is a hybrid approach to software development and distribution, combining elements of both open source and closed source paradigms. In this model, a company offers a "core" version of its software as free and open source, giving users access to basic functionality and source code. Simultaneously, the company develops and sells proprietary add-ons or an enterprise version that includes advanced features, enhanced security, scalability, or integrations-features often essential for business use.

This approach can accelerate adoption by lowering the barrier to entry, it introduces significant limitations. The free version typically lacks critical features, and users must pay to access the full functionality. Importantly, the proprietary extensions are not open source, meaning their code cannot be audited, modified, or redistributed by users. This structure can restrict flexibility, limit community contributions, and create a dependency on the vendor for ongoing support and updates.

The Controversy and Risks of Open Core

The open core model is controversial within the open source community. Critics argue that it dilutes the spirit of open source by withholding essential features behind a paywall, leading to a "bait-and-switch" experience where users are enticed by the promise of open source but ultimately pushed toward proprietary solutions. This can result in vendor lock-in, where a business becomes dependent on a vendor's proprietary extensions, losing the freedom and control typically associated with open source software.

For small businesses, the risks are particularly acute. Open core vendors may discontinue support for the free version, restrict access to code, or change licensing terms to force users onto paid plans. The lack of transparency can make it difficult to assess the true cost and viability of the solution over time. Furthermore, the boundary between free and paid features is often unclear, leading to unexpected costs or technical limitations as business needs evolve.

The risks of open core go beyond just missing features. Because the vendor retains control over the most valuable parts of the software, you are exposed to several potential problems. First, there’s the risk of vendor lock-in. Once you’ve built your business processes around the proprietary features, switching to another solution can be costly and time-consuming. You may have to retrain staff, migrate data, and even rewrite integrations.

Second, the vendor can change the terms at any time. They might increase prices, restrict access to certain features, or even discontinue the open source version altogether. There have been numerous cases where vendors have changed their licensing model after building a user base, suddenly making previously free features paid or placing new restrictions on use.

Third, there’s the issue of transparency and security. With closed source extensions, you can’t audit the code for security vulnerabilities or compliance issues. You have to trust the vendor’s assurances, which may not be enough for businesses in regulated industries or those with strict security requirements.

Understanding Open Washing

Open washing refers to the practice of marketing software as "open source" when, in reality, it does not meet the fundamental principles of openness and transparency. This can involve releasing only a portion of the code, withholding critical components such as training data or configuration files, or imposing restrictive licenses that prevent meaningful community participation or modification.

In the context of AI and machine learning, open washing has become increasingly prevalent. Companies may release models or tools as "open" but provide limited insight into their inner workings, training data, or update mechanisms. This lack of transparency undermines the core values of open source and can create compliance, security, and operational risks for businesses that rely on these solutions.

What Small Businesses Should Watch Out For

To avoid falling into the traps of open core and open washing, small businesses should approach open source solutions with a critical eye. It is essential to verify whether the software is truly open source by reviewing the licensing terms, the availability of the full source code, and the presence of an active, independent community. If advanced features or support are only available through proprietary extensions, businesses must weigh the long-term implications of vendor dependency and potential lock-in.

Transparency is key. Genuine open source projects provide clear documentation, open development processes, and community-driven roadmaps. In contrast, open core and open-washed products often lack transparency, restrict contributions, and prioritize commercial interests over user empowerment. Small businesses should also consider the sustainability of the project, the track record of the vendor, and the availability of alternative solutions that adhere more closely to open source principles.

Identifying open core and open washing requires a careful, skeptical approach. Start by examining the license: is it a recognized open source license approved by the Open Source Initiative (OSI), such as MIT, Apache, or GPL? If not, be wary. Even if the license looks open, check for clauses that restrict how you can use, modify, or distribute the software.

Next, look at the project’s repository. Is the full source code available, including all modules, extensions, and build scripts? Can you build the software from source without relying on proprietary binaries or services? Are there clear instructions for deployment and customization?

Assess the community as well. Are there independent contributors, or is all development controlled by the vendor? Is there a public roadmap, issue tracker, and transparent decision-making process? If everything flows through the vendor, the project may not be as open as it appears.

For open core products, pay close attention to the feature matrix. Are critical business features only available in the paid version? How much of the functionality is truly open source? If you anticipate needing advanced features, calculate the total cost of ownership, including potential upgrade fees and support costs.

Protecting Your Business

To safeguard your business, always conduct a thorough due diligence process before adopting any “open” software. Insist on seeing the full source code and verifying the license. Test the software in your environment to ensure it meets your needs without requiring proprietary add-ons. Engage with the community to gauge its health and independence.

If you discover that a product is open core or open washed, weigh the risks carefully. Sometimes, the benefits may outweigh the downsides, especially if the vendor is reputable and the paid features are competitively priced. However, always have an exit strategy. Ensure you can export your data and migrate to another solution if needed.

Consider supporting genuine open source projects. These projects rely on community contributions and often provide greater transparency, flexibility, and long-term sustainability. When contributing financially or through code, you help ensure the health of the ecosystem and reduce your dependence on any single vendor.
