Why this matters for digital sovereignty
Office productivity suites hold most of an organisation's documents, spreadsheets and presentations, and a US-based provider brings those under the CLOUD Act regardless of storage location. Check where files and backups actually sit, who ultimately owns the vendor, and whether offline or self-hosted collaboration is possible.

- ONLYOFFICEEU sovereign
ONLYOFFICE is a Latvian office suite that was open source (AGPLv3) until version 9.4 (May 2026), when additional Section 7 terms were introduced requiring logo retention in forks while simultaneously denying trademark rights. The Free Software Foundation ruled this a prohibited further restriction under AGPLv3 Section 10, breaking OSI compliance. The software is now effectively source-available with restrictions. ONLYOFFICE Workspace Cloud was discontinued on 2 March 2026; the successor DocSpace (cloud and self-hosted) continues.
