> Based in Riga, Latvia, OnlyOffice owner Ascensio System SIA was a subsidiary of Russian-based New Communication Technologies[34] (not to be confused with the company The New Cloud Technologies, which develops an unrelated office suite named MyOffice (Russian: МойОфис)[35]). Due to EU economic sanctions targeting Russia, European organizations that used the commercial version of OnlyOffice were prohibited from doing so.[0]

I'm on LibreOffice 26.8 with the new ui, it is absolutely equivalent with zero geopolitical risk coming from the Atlantic or the Urals.

And if you need cloud integration there is UK based Colabora and now also LibreOffice Online.
