And now the document foundation, which is behind LibreOffice (the active fork of the dead OpenOffice) is also german based. And they put a lot of work into it, also the modernisation. But to be honest, I am not sure, if they could ever become a serious competition. I think they would have to do a fresh UI start and be 100 microsoft office compatible. Then they would have a chance. With more official backing, this is maybe remotely possible, but I do not count on it. Rather political pressure for a slight modification for Microsofts operations for germany.
