We spent 20+ years on defining, supporting and promoting ODF and LibreOffice as open standard and open source solution for #DigitalSovereignty and now some tech bros decide to fork OnlyOffice (which uses Microsofts OOXML as internal format) instead of helping https://www.opendesk.eu/en/about and the Collabora people prefer infighting with The Document Foundation. Le sigh. (slightly exaggerated, but reflects my disappointment)

I thought they choose OnlyOffice because of its userfriendly and recognizable interface.

Not based on any hard intel, just a hunch.
