More proactive promotion of and investment in Open Source Software (OSS) at the level of the European Union and national governments would not only boost economic growth in Europe. It would also stimulate innovation, facilitate the emergence of a successful European information technology industry rooted in a wide ecosystem of Open Source companies and creators of all sizes and create jobs in the software sector and increase Europe’s ability to determine and shape its own digital future. These were the clear conclusions of a recent study published by the European Commission.
