Germany is a federal republic and some politics are centralized and others not. Compared to some other countries in, say, Europe, Germany is pretty decentralized. That the city Munich experiments with Linux is exactly because of this.

This has nothing to do with assimilation of power in Brussels, but getting rid of Microsoft office and get more public money spend on 'free' and or 'open source' software.

It is our money which keeps cities, states, countries and the EU budgets going.
