Regarding downvotes, I'll take a guess - OP's post says:
>[MS office] can use [ODF] as the default for all new files. At least since the 2010 version. If even MS recognizes that ODF has won, we have no reason to use OpenXML.
That leap of logic just doesn't compute... By the same token, since OpenOffice / LibreOffice can be set to use OpenXML as default, they've admitted that OpenXML has won. Being able to use each other's formats should be viewed as an attempt to move into each other's markets, not as declaration of victory.
OpenOffice has to support OOXML because they have always positioned themselves as supporting everything under the sun. They supported .doc from the start.
Microsoft has traditionally supported only their own formats, so their decision to adopt an open source format is much more meaningful than OpenOffice's decision to support OOXML.
