@MichlFranken The foundation of ONLYOFFICE was laid in Russia, and until 2023, the company behind ONLYOFFICE was under Russian ownership. Only after that was the official structure changed, with a holding company in Singapore designated as the new owner. Even now, many of the developers still work from Russia, and there is ongoing discussion about the transparency and origin of the software.

PLEASE have a good look at ONLYOFFICE and LibreOffice!
