More than that, it’s standardization made MS panic and pseudo-standardize their OOXML (.docx & co.) a year later, since some govt wanted to switch to ODF back in 2007, instead of relying on sone proprietary format. The pseudo, because most of the format is proprietary extensions (and only the strict variant, which MS doesn’t set as default), which made the standardization a …unusual process.

Yes and they they switched form MsOffice to Libre like few years ago

Isn’t it odt that LibreOffice uses? I wonder what the difference is.
