The Crisis in the Open Source Ecosystem and a New Paradigm for Sustainability

Why Is Open Source in Crisis?

Open source is in crisis because the code the whole digital world runs on is maintained by underpaid, burned-out volunteers while large companies profit from it without giving back. As of 2026, the 'Sustainability of Open Source' is the most urgent survival issue facing the entire IT industry, and the responses range from defensive licenses to foundation funding and corporate contribution programs.

Almost all software we use today, from the Google search engine to smartphone operating systems and even the core infrastructure of banks, is built on 'Open Source' code. It is virtually impossible to build a service in modern software development without using a single open-source library.

Yet this invisible infrastructure is experiencing severe cracks. While global conglomerates generate trillions of won in profits, numerous core maintainers of the open source they use are suffering from 'passion pay' and burnout, leading to a surge in cases where they abandon or neglect projects.

What Did the Log4j Incident Reveal About Open Source Security?

The 'Log4j vulnerability (Log4Shell) incident' of a few years ago showed the world how fragile the open source ecosystem is.

Log4j is a very universal and basic open source library used to write logs on millions of Java-based servers worldwide. When a fatal security flaw was discovered in this single small library, the services of global IT giants such as Amazon, Apple, and Microsoft were simultaneously exposed to hacking threats, an unprecedented situation.

An even more shocking fact is that the core components of this global infrastructure were being maintained by just a few individual developers, sacrificing their weekends and sleep, unpaid or relying on small donations. Forcing individuals who receive no financial compensation to bear the responsibility for perfect security is a clear structural contradiction.

What Is the Free-Riding Problem in Open Source?

Free-riding is the imbalance at the core of the crisis: companies capture the profits from open source while the people who create it receive almost nothing.

Massive cloud companies or software companies take well-made open source databases (e.g., Redis, Elasticsearch) or tools, package them as their own commercial cloud services, and generate massive profits. However, in many cases, not even a tiny fraction of those profits was returned to the original authors or the community. As those who produce value and those who monopolize the profits become separated, the open source ecosystem is gradually drying up.

How Is the Industry Making Open Source Sustainable in 2026?

To overcome the crisis, the industry is combining license policy changes, new sponsorship models, and workplace contribution programs.

① The Emergence of Defensive Licenses such as the Server Side Public License (SSPL)

Major open source companies such as MongoDB, Redis, and HashiCorp (Terraform) have abandoned traditional fully open licenses (Apache, MIT, etc.) to prevent indiscriminate commercial use by massive cloud vendors. While they keep the code open, they are converting to more restrictive licenses (SSPL, BSL, etc.) that require payment when commercializing it as a cloud service. This is a desperate measure for survival, but it is also sparking fierce debates, with some arguing that "the true meaning of open source is fading."

② Structural Sponsorship at the Corporate Level (Open Source Foundations)

Moving beyond simple donations, companies are increasingly investing large funds into independent non-profit foundations like the Linux Foundation or the Apache Foundation to create ecosystem funds. These funds provide support equivalent to a stable salary to maintainers of important but unnoticed infrastructure-level open source projects, allowing them to focus on development.

③ A Culture of Recognizing Open Source Contributions as Key Performance Indicators (KPIs)

Mature tech companies are spreading a culture of encouraging their developers to spend a certain percentage of working hours contributing (fixing bugs, documentation, etc.) to the open source projects the company uses, and officially recognizing this as a performance metric in HR evaluations.

How Can We Prevent a Tragedy of the Commons?

Preventing a tragedy of the commons requires companies to return fair costs and effort to open source. Open source is not simply 'a piece of code someone made for free'. It is the common intellectual asset of humanity and a massive 'digital infrastructure' built through the collaboration of countless intellects.

Just as we pay taxes to maintain roads and bridges, software companies must now give back to the ecosystem that serves as the foundation for their profits. If we do not improve the current precarious structure that relies solely on the dedication of open source maintainers, second and third Log4j incidents could visit us again at any time.
