LibreOffice slams rival Euro-Office as a ‘de facto ally’ of Microsoft lock-in — as concerns over possible Russian interference rise

• Euro-Office defaults to Microsoft’s OOXML format, encouraging vendor lock-in
• LibreOffice calls the European sovereign offering a blatant “freeware” copy of MS Office
• Euro-Office and its origins, OnlyOffice, are mostly created by Russian developers

The Document Foundation – the organization behind LibreOffice – has publicly criticized Euro-Office over concerns that it does not genuinely promote European digital sovereignty despite its marketing as a viable European alternative to the likes of Microsoft Office.

LibreOffice described Euro-Office as a “freeware clone” of its Big Tech rival, claiming its strategy is to mimic Microsoft’s interface and workflows.
