Some days ago folks at the Document Foundation announced that the north-German state of Schleswig-Holstein switches from Windows to GNU/Linux, and from MS Office to LibreOffice. I think this is a right move, because proprietary software doesn't have a place in government, schools and healthcare, except in some really special places where there is no open source alternative.
Why? Because at these places they should save information in a way which is readable even 30 or 50 years later. How can you do this with the undocumented, proprietary M$Word DOC format? Will you use a virtual machine with Windows XP to open it? Ha-ha...
It might be very interesting, that in similar situations, crazy brainstorming starts at the local Microsoft sales team. Will they even pay them to not move away from Microsoft software©®™?
A short list of governments who moved to GNU/Linux is available at this link. Should we work to make this list longer?
