Europe's Euro-Office sparks open-source fight over logo and formats

Euro-Office, a European office suite forked from ONLYOFFICE, has triggered a dispute: ONLYOFFICE suspended its eight-year Nextcloud partnership over a logo change, while the FSF backed the fork. The Document Foundation called Euro-Office a de facto Microsoft ally for defaulting to DOCX, though its ODF support is rated limited.

• Euro-Office is an ONLYOFFICE fork that works as an editor without storage or permissions
• ONLYOFFICE ended its Nextcloud partnership over the logo clause violation
• In May 2026 ONLYOFFICE rewrote its extra terms but kept the About-page credit rule
• The Document Foundation criticized Euro-Office's DOCX-first approach
