The Struggle is real, Free of Charge != Cost-Free
The Eclipse Foundation is home to some of the world’s most widely adopted open source projects, including Jakarta EE, Eclipse IDE, Eclipse Temurin, and many more. These technologies power critical infrastructure across industries. Often free of charge. But does “free” really mean cost-free?
As projects like Eclipse Temurin approach milestones such as 600 million cumulative downloads, the disconnect becomes clear: while enterprise adoption is strong, financial support from those same users is often missing. This talk explores the reality behind the sustainability of open source and how the Eclipse Foundation supports its projects through a unique combination of revenue models, all while preserving vendor neutrality..
Key focus areas will include:
Explaining the Eclipse Foundation's model: How the membership system and revenue-generating strategies, such as sponsorship, SWAG stores and targeted funding, are helping sustain the project.
Understanding enterprise users: Who they are, their familiarity with the open-source ecosystem, and whether they want to support a foundation or simply pay for software.
Highlighting the true costs: The infrastructure costs associated with a high-demand project like Temurin and raising awareness about the financial and operational savings enterprises enjoy by using it.
By exploring the relationship between free-of-charge software and the real costs of its development and maintenance, this talk will show how users can give back and why doing so is vital to the project's long-term success.
Diversity in Open Source as a Sustainability Goal
It's time to acknowledge a common trend: Open Source average contributor profile is middle-aged, white male, Western European, or North American. This demographic is not unique to Eclipse Foundation —it is a widely recognised stat among open source projects.
Open source global adoption needs to be linked to Global development. Different audiences have different needs and problem-solving perspectives.
Diversity in open source is about more than just gender—it encompasses age, language, race, sexuality, disability, and social backgrounds (education, geography, religion, internet access, environment, etc.).
In this session, we invite all our community members to help us create the basis to define a more diverse approach for our contributors and project development process.
Let's lower the barrier and work on project sustainability through diversity.

Building a successful open-source project is no easy feat—it requires more than just technical excellence.
As the Program Manager for Eclipse Adoptium, I’ve encountered the ups and downs of fostering a thriving open-source ecosystem.
In this talk, I’ll share the dos and don’ts of community management based on real-world lessons from Adoptium’s journey. We’ll discuss the challenges of keeping a community-engaged, balancing the need for rapid innovation with quality control, and managing the inevitable growing pains of scaling a project. You’ll learn how to navigate common pitfalls and leverage best practices to ensure your project remains healthy and sustainable. Through examples such as our AQAVit initiative, which balances quality with performance, and strategies for secure, reproducible binaries, I’ll show how community-driven collaboration can lead to better outcomes—when done right.
This talk is for project leads and communities managers looking for practical, actionable insights on what it really takes to build and sustain a successful open-source project.
How Open Source contribution programs benefit both mentors and participants
Eclipse Adoptium is a top-level open source project under the Eclipse Foundation where Temurin and AQAvit are developed with assistance by ‘new to open source’ contributors under industry mentorship. In this session, we share our experience mentoring new contributors through programs such as Outreachy, Google Summer of Code, and CANOSP. We will survey these programs and share both challenges and success stories. There are some vivid examples demonstrating the advantages for both participants and the open source projects.
All of these open source programs have similarities but also their own unique flavor, with variations in goals and term lengths. Outreachy provides paid internships to people subject to systemic bias and impacted by underrepresentation in the technical industry where they are living. Google Summer of Code focuses on bringing new contributors into open source software development. Canada Open-Source Projects (CANOSP) is an academic program that connects top students from Canadian universities to work on open-source projects. In all cases, the value of collaborating with new contributors who bring a diversity of experience and world view is the essence of open source. This talk gives practical tips on working with open source programs but also serves to enlighten others on the mutually beneficial reasons they should engage.
