Why Open Source Contributions Matter in Europe

Open Source as a Core Part of the Tech Industry

Open source software plays a key role in Europe's digital economy. It sparks innovation, lowers costs, and eliminates dependency on specific vendors. In fact, surveys show that 76% of respondents believe open source is more secure than proprietary software, with trust in its security growing from 73% in 2023 to 76% in 2024. Its adaptability also allows businesses to customize tools to meet their exact requirements.

But open source isn't just about functionality - it’s a strategic asset. Over half of European survey respondents report increasing benefits from open source each year. Sectors like IT (37%), government (36%), and higher education (30%) stand out as areas where further investment could yield significant advantages.

Gabriele Columbro, Executive Director of Linux Foundation Europe, captures this sentiment perfectly:

"With open source now at the heart of Europe's technological ecosystem, this report provides unique and immediately actionable strategic insights for private and public sector actors, as well as individual contributors. The findings reinforce that open source's value goes way beyond code - it's an essential pillar supporting Europe's digital future, social and economic growth."

Europe's Open Source Contribution Numbers

Europe has become a powerhouse in the global open source community. For instance, the United Kingdom represents 26% of EU companies contributing to GitHub - a figure more than double Germany's 13%. A 10% increase in open source contributors could lead to a GDP boost of 0.4%–0.6%, the creation of over 600 ICT startups, and around $100 billion in economic value.

What sets Europe apart is its grassroots approach. Unlike industry-driven models seen elsewhere, Europe's focus on community-driven development fosters local innovation. Mirko Boehm, Senior Director of Community Development at Linux Foundation Europe, highlights this unique motivation:

"Many contributors are motivated by self-learning and professional growth, with open source offering opportunities to build skills and collaborate on real-world projects."

This is backed by data - 74% of individual respondents cite learning and personal development as their main reasons for contributing to open source. Wealthier European nations also lead in active developers per 100,000 residents, showcasing a decentralized model of innovation.

The momentum behind open source in Europe continues to grow. In January 2025, the European Open Source Academy was launched to encourage both the use and development of open source software and hardware. A notable example of European achievement in this field is Daniel Stenberg, founder of cURL, who received the European Open Source Achievement Award for his work on tools and libraries that enable data transfer using URL syntax. These tools are essential for internet communication and are used by billions every day. His recognition underscores the global impact of European open source efforts and the career opportunities it creates for developers.

These contributions provide a solid foundation for examining how open source engagement translates into better salaries.

How Open Source Contributions Affect Salaries

Problems and Gaps in OSS Salary Benefits

Open source software (OSS) contributions can lead to higher salaries for software engineers, but these financial benefits are not shared equally among all contributors. Several factors play a role in determining who reaps the rewards.

Uneven Distribution of Salary Gains

The financial rewards of OSS contributions tend to be concentrated among a select group of contributors. This reflects a broader trend of wage inequality, where economic benefits often accrue to specific groups rather than being distributed evenly.

One key factor contributing to this disparity is geographic location. For instance, countries like Iceland, Switzerland, and Norway boast the highest number of OSS developers per 100,000 inhabitants. Within these countries, OSS activity is often centered in major tech hubs like Berlin, Amsterdam, or Stockholm. Developers in these areas typically enjoy higher salary premiums compared to those in smaller cities or rural regions. These geographic and demographic differences create market-driven variations in salaries based on specific technical skills and opportunities.

Technology Alignment and Market Demand

Beyond geographic factors, the alignment of a contributor's skills with market demand plays a significant role in determining salary outcomes. Mastery of in-demand technologies can significantly impact earning potential.

Employers often face challenges finding OSS talent, which drives up salaries for those with specialized skills. Expertise in areas like cloud computing, containerization, and cybersecurity commands higher salary offers and boosts negotiation leverage, especially for professionals with strong security knowledge.

Certifications also help bridge gaps in market demand. Formal credentials provide evidence of expertise and help align a contributor’s skills with industry needs, making them more competitive in the job market.

In short, the financial impact of OSS contributions is less about the quantity of contributions and more about how well a contributor’s skills align with current market demands. Addressing these gaps is crucial for professionals looking to maximize their career growth through OSS involvement.
