Executive Summary

The Document Foundation (TDF) has strongly criticized the release of the open-source web office Euro-Office. Italo Vignoli, co-founder of TDF behind LibreOffice, accuses the project of using Microsoft's proprietary OOXML format by default. Despite promises of sovereignty, this effectively strengthens Microsoft's lock-in strategy. Nextcloud and Ionos, which are leading the development of Euro-Office, argue instead that compatibility with Microsoft formats is initially necessary for users. They plan to gradually transition to supporting open ODF standards.

The dispute reveals a core dilemma of European sovereignty projects: whoever uses proprietary formats for compatibility effectively strengthens the monopolist Microsoft – regardless of European leadership of the product. TDF argues that genuine change begins only with open standards. In contrast, Nextcloud and Ionos rely on pragmatic migration rather than ideological purity. The debate is further sharpened by LibreOffice plans to compete with a web office, which clarify the economic interests of the TDF.

Detailed Summary

Vignoli criticizes the business model of Euro-Office fundamentally in his open letter: the project uses OOXML "by default and exclusively," a format that Microsoft alone develops and controls. This makes Euro-Office "de facto an ally of Microsoft" and prevents genuine European digital sovereignty. Vignoli argues that only open standards such as ODF format (Open Document Format) can create true independence. He also criticizes the project's communication, which portrays itself as "the first open-source office suite developed in Europe" – a statement he calls misleading regarding the history of OpenOffice and LibreOffice.

Nextcloud and Ionos justify their approach with practical constraints: currently, there is no solution that combines "complete compatibility with Microsoft formats, familiar user interface, and genuine digital sovereignty." A Nextcloud spokesperson explains that the company also views proprietary formats as an obstacle to sovereignty, but must first reach users on an open platform. This would allow organizations to then gradually migrate to ODF. Development at Euro-Office therefore focuses on improved ODF support, with the goal of making ODF the standard in the long term.

A competitive layer complicates the debate: TDF is itself developing plans for a web office based on LibreOffice. Collabora Office (also based on LibreOffice) finds itself under pressure in the new Nextcloud Hub – users can now choose between Collabora and Euro-Office. Collabora CEO Michael Meeks highlights Collabora's "excellent interoperability" and criticizes the fact that OnlyOffice code (the basis of Euro-Office) opted for Microsoft's DOM (Document Object Model). This decision brings "significant business and technical compromises."

Key Statements

  • Proprietary Microsoft formats in open-source projects can undermine genuine digital sovereignty, even when development is led by Europeans.
  • Pragmatic design (compatibility over standards) and ideological purity (standards over compatibility) are opposing strategies that both have validity.
  • The market for European office suites is fragmenting; competition between the LibreOffice ecosystem (Collabora, TDF plans) and Euro-Office is intensifying.

Critical Questions

  1. Evidence/Source Validity: How broad is the technical analysis of Vignoli's criticism – is the assessment that OOXML standard usage strengthens Microsoft's lock-in based on independent studies or individual opinion?

  2. Conflicts of Interest: To what extent could TDF's own development of a web office product motivate the severity of criticism of Euro-Office, rather than purely technical concerns?

  3. Causality/Alternatives: Can organizations truly gradually migrate to ODF if Euro-Office remains the OOXML standard, or does lock-in already occur through usage familiarity?

  4. Feasibility/Side Effects: If Nextcloud prioritizes ODF support – when can production-ready ODF compatibility be expected, and can users work without Microsoft format support until then?

  5. Data Quality: What order of magnitude of users and organizations is currently being addressed by Euro-Office, and how realistic is the migration roadmap to open standards?

  6. Interest Alignment: Does the broad European public administration share TDF's philosophy (standards-first), or does it prioritize practical compatibility as Nextcloud argues?
