The “Euro-Office” initiative constitutes a fork of ONLYOFFICE software based on its code.
According to publicly available materials, including the above, certain ONLYOFFICE licensing terms appear to have been altered or removed.
This constitutes a breach of the applicable license.
Accordingly, we state the following.
Since 2016, ONLYOFFICE has distributed its software under the terms of the GNU Affero General Public License v3 (AGPLv3), a widely recognized copyleft model designed to ensure a balance between openness of the code and protection of the rights of the copyright holder.
Essentially, AGPLv3 requires that the same license be preserved upon distribution, that the source code be disclosed - including where the software is provided as a service (SaaS) - and that copyright notices and license attributions be retained.
Pursuant to Section 7 of AGPLv3, the copyright holder is expressly entitled to impose additional conditions. In the case of ONLYOFFICE, such conditions include, in particular:
- the obligation to retain the original product logo (Section 7(b));
- the denial of any rights to use the copyright holder’s trademarks (Section 7(e)).
Such additions to the License were implemented on May 25, 2021, and can be found at line 655 of the License.
AGPLv3 expressly permits the inclusion of such additional conditions, which, upon distribution of the software, apply together with the core license terms as a single, indivisible, and enforceable legal framework.
Accordingly, access to and use of the code is strictly conditional upon full compliance with all applicable terms - both standard and additional.
Any argument that a modified or derivative version of the software may be distributed under a “pure” AGPLv3 license, excluding the additional conditions imposed pursuant to Section 7, is legally unfounded.
The right to create and distribute derivative works arises solely from the license grant. Such grant is conditional and indivisible. Accordingly, any derivative work based on the original ONLYOFFICE code may be created and distributed only in compliance with all applicable license terms, including the additional conditions.
The creation of a derivative work does not give rise to an independent licensing regime free from the conditions under which the original code was obtained.
In other words, AGPLv3 does not permit selective application: a recipient either accepts AGPLv3 in its entirety, including all additional conditions, or acquires no rights to use the software.
Any removal, disregard, or unilateral “exclusion” of conditions imposed under Section 7 constitutes use beyond the scope of the granted license and therefore a breach.
Under Section 8 of AGPLv3, any breach of the license terms results in the automatic termination of the rights granted thereunder.
In the absence of a valid license, any further use of the software is unauthorized and, as such, constitutes an infringement of the copyright holder’s exclusive rights.
Characterizing such additional conditions as “unenforceable” or “non-obligatory” does not alter their legal nature. These conditions form part of the license grant itself, and compliance with them is a condition for obtaining and maintaining the rights under AGPLv3. Their validity is not subject to unilateral assessment by a recipient of the code.
