'The German city of Munich, which received much popularity back in the day when it first ditched Microsoft's services in favor of open-source software, has now agreed to stop using Linux and switch back to Windows.'
Update <http://www.theregister.co.uk/2018/01/04/munich_linux_costs_ownership/>: That decision will cost the city upwards of €50m plus another €50m to revert to Windows 10, according to reports. The bill results from a combination of buying Windows 10 licences and converting some 12,000 LibreOffice templates and macros along with developing a new templating system for Microsoft Office. The article also quotes instances of many other Government departments in France, the Netherlands, Italy and Denmark successfully making large-scale deployments of Linux OSes and LibreOffice. The Document Foundation maintains a list here <https://wiki.documentfoundation.org/LibreOffice_Migrations>. I suppose Munich can serve as an opposite data point: what it would cost to migrate from Linux to Windows.
