@teto @niobleoum @matty Libreoffice can save to docx and all the other proprietary formats.

Libreoffice merely has a clickthrough that suggests you save to a free format instead - you just dissmiss it and save to the format you want.

Onlyoffice is libreoffice as SaaSS, with proprietary software added.

Typical braindead behavior, considering a .docx was designed to easily contain a virus, while .odf doesn't really encode virus's well.
