What?!
All that noise about Switzerland mandating usage of open sourced software in gov (there was a great step, but it's far from mandating anything) was already weird, now we are switching to linux? And caring about security and fiscal responsibility? There has to be another country called Switzerland than the one I live in.
You're right, I believe the only thing Switzerland mandated (or wants to mandate?) is for projects built FOR the government to be open sourced - and even then, there are exemptions.
Of course, unlike you, I don't live in Switzerland, so I'm probably not as informed.
