Tdf is right when it comes to Europe needing to switch away from ooxml, but their attacks against Euro-Office are out of place imho. Yes, in a perfect world, we all switch to LibreOffice and start using odf today, but in the real world, already showing users* that there are alternatives to Microslops office suite will be a huge challenge, and Euro-Office can be an ally here. This infighting however only benefits Microslop.
