It's interesting because some cities publicly documented their switch to Linux, then came back to MS things (for some reasons). But in the end having open source, untied software is of political importance if you want to avoid being tied.
Munich never switched back, which is probably the city you are talking about, but Microsoft has been throwing millions of dollars into both defamatory propaganda against the city and attempts to either elect officials to force them back to Windows or to buy off key officials to make it happen.
It is extremely crooked when you read the narrative as its unfolded over the last decade. Microsoft is extraordinarily aggressive in maintaining its monopoly in the public sector.
Yea I remember reading about this in Linux Format magazine (yea I pick up a copy occasionally when at the bookstore...great read on all things Linux, and FOSS) a few years ago. It is crazy how far Microsoft will go if the stories are true. If Munich wants to use LibreOffice, then let them, or maybe make an OS that doesn't require an almost unfathomable amount of resources.
