In a blog post, OnlyOffice publicly expresses its anger. Euro-Office is using technology derived from OnlyOffice in violation of license terms and international intellectual property law. OnlyOffice is subject to the AGPL-v3 license and imposes further conditions to ensure transparency and appropriate source attribution. According to OnlyOffice, these include retaining the OnlyOffice trademarks in derivative works, providing appropriate source attribution to the original technology, and fully complying with open-source requirements for distributing the software.



Easy fix: Don’t fork OnlyOffice. Start your own office suite and just happen to port over some parts of the code base that do not include any logos. Same, same but different.
Or just fork Libreoffice online…
They already explained why they didn’t.
And their argument was quite shallow
Or LLM cleanroom copy it, like the internet did when claude code source was leaked into other languages like rust
