This is nonsense, and a very weaselly use of the passive to avoid saying who did what. ODF was adopted as a standard. MS dropped it in favour of OOXML, which was accepted as an international standard amidst much controversy. The ODF standard was
never dropped by anyone other than MS, and development on ODF continues.
Apparently you missed some of my earlier comments.
Microsoft did not drop ODF support from Microsoft Office for Windows. ODF support is present in the past 3 versions of Microsoft Office for Windows: Office 2010, 2013 and 2016. Microsoft also supports ODF in the web version of Microsoft Office.
Microsoft did not drop ODF support from Microsoft Office for Mac. The Mac version has simply never supported ODF file formats. The work-around for Mac users is to open ODF files in the free web version of Microsoft Office or use LibreOffice, NeoOffice, or
OpenOffice.
Recently Microsoft opened a site where feature requests can be made and voted on. So far no one has made a request for supporting ODF, so if this is something you wish to see Microsoft do, by all means please express your wish here:
Word for Mac
Excel for Mac
PowerPoint for Mac
ODF support is just one of hundreds of features Microsoft has left out of the Office for Mac version compared with Office for Windows.
