Lyon Ditches Microsoft, Embraces Open Source for Digital Sovereignty

The city of Lyon is phasing out Microsoft software, opting for open-source alternatives like OnlyOffice, Linux, and PostgreSQL to reduce reliance on US tech and strengthen digital sovereignty. This move utilizes the 'Territoire Numérique Ouvert' suite, developed with SITIV and Lyon Metropolis, already used by thousands across nine local governments. Lyon joins Copenhagen and Aarhus in this trend, highlighting a growing push for public-sector tech autonomy in Europe.
