In Europe they launched Euro‑Office—a suite of office programs based on the OnlyOffice code

Euro‑Office – a new European office suite

1 What is Euro‑Office?
A consortium of three European companies – Nextcloud, Ionos and Proton – has created a set of office applications called *Euro‑Office*. The project’s foundation is the open source codebase *OnlyOffice*.

The package includes:

All components are compatible with both Microsoft Office formats and open standards (ODF). A pre‑release is already available on GitHub; the official Euro‑Office 1.0 is slated for launch in summer.

2 Why this matters to Europe
The project is part of a broader digital sovereignty strategy:

- reduce dependence on American software vendors,
- ensure control over critical infrastructure and data,
- give government agencies and businesses the ability to manage their own code.

For many organizations, having control over source code becomes equivalent to the functional level offered by foreign competing products.

3 Licensing and conflict with OnlyOffice
OnlyOffice, which is the “parent” of Euro‑Office, accused the fork of violating the terms of GNU AGPL v3.

> *“Any argument that a modified version can be distributed under pure AGPL v3 without additional restrictions is legally unfounded… Any derivative work must comply with all license conditions, including addenda.”* – stated OnlyOffice developers.

Thus a dispute arose over whether it is permissible to freely fork and distribute the code without changing the license.

4 Trust and transparency issues
Euro‑Office emphasizes that:

1. OnlyOffice has Russian roots: most of the source code was written by developers from Russia.
2. Under current geopolitical tensions, this complicates collaboration.
3. Lack of transparency in the development process undermines trust.

Moreover, Euro‑Office claims that contributing to OnlyOffice is “impossible” or “not recommended”, and that build instructions are unreliable and outdated.
OnlyOffice counters these statements, noting that it has moved its operations to Latvia and is open to collaboration.

5 Core conflict
The crux of the dispute: the right to fork versus commercial and political realities.

- For Euro‑Office it’s a path to software independence under the motto “Made in Europe”.
- For OnlyOffice it illustrates how mistrust and license interpretation can lead to conflict over open source code.

Conclusion
Euro‑Office represents an attempt to create a fully European office suite based on an existing open‑source solution. At the same time, the project has faced legal claims that sparked debate about licensing and trust in the global developer community.
