[STUDENT POLICY BRIEF] European Open Source Software Policy as a Countermeasure to Big Tech Dominance

By Simonas Zilinskas-Inta, Lukas Hübner, Barbora Bromova & Lionel Perruchoud


The Digital, Governance and Sovereignty Chair publishes, on a regular basis, the finest essays and papers written by Sciences Po students in the course of their studies.

This Policy Brief has been selected as one of the best works written during the course taught by Pr Florence G’sell “Comparative Approach to Big Tech Regulation” in Spring 2023.


This policy brief examines the role of open source software (‘OSS’) in the European Union (‘EU’) and its potential to enhance digital sovereignty, innovation and efficiency. OSS offers several advantages over proprietary software, such as:

• Lower costs and higher efficiency;

• Greater transparency and security;

• More alignment with European values and principles.

However, the paper identifies several challenges that OSS faces, such as:

• Lack of awareness and visibility about the current and potential roles of open source;

• Lack of funding and incentives to contribute;

• Governance problems in open source project communities.

The paper reviews existing legal frameworks and policy initiatives at the EU and national levels that support OSS development and adoption. It highlights:

• The licence system that facilitates the sharing and reuse of OSS across public administrations;

• The Open Source Software Strategy 2020-2023 that outlines the EU’s vision and actions for OSS;

• The German Sovereign Tech Fund that provides financial and technical support for OSS projects.

The brief concludes with some policy recommendations to improve the current strategy and foster a more robust and diverse OSS ecosystem in Europe to fully harness the benefits of open source software. The recommendations include:

• Inverting the standards for public procurement of proprietary software and prioritising OSS solutions;

• Improving software catalogues for trusted OSS and increasing their usability;

• Integrating OSS into EU strategic goals and programmes, such as open science, Horizon Europe, Next Generation Internet, and Interoperable Europe Act;

• Scaling up the Sovereign Tech Fund model at transnational, national and regional levels to address specific needs and opportunities.
