@libreoffice so LibreOffice will stop supporting OOXML format and no longer do marketing with the fact it can also handle OOXML documents to attract newcomers? The marketing argument IMO is therefore not fully fair and debatable (I do favor ODF, but there is inconsistency in the argumentation I feel). In the end the only difference is the chosen default format, but also LibreOffice supports both ODF and OOXML.
Just focus on governments prioritizing ODF format instead of focusing on OOXML? It's always stronger to advocate in favor of something then against something. LibreOffice has done A LOT to make ODF more known and the ODF (foundation) deserves credits for that! Think positive!
