This is EU, what else do you expect? European officials saying they're ditching Windows has become a ritual:

> The German Foreign Office first moved over to Linux as a server platform in 2001... the Foreign Office of Germany made the announcement (translated news report) that it is migrating away from Linux back to Windows as its desktop solution.

> By December 2013, the city concluded the migration, with over 14,800 desktops running on LiMux... In November 2017, nearly four years after the conclusion of the migration, the Munich city council adopted a decision overhauling the move. All equipment was to be refitted with Windows 10 counterparts by 2020

> WIENUX[2] is a Debian-based Linux distribution developed by the City of Vienna in Austria... until 2008 when the download page was taken offline.

> Birmingham City Council piloted OSS on hundreds of desktops in its public libraries in 2005-6. It originally planned to install Linux ... but this was over-ambitious for the time frame of the project and compatibility problems meant that the open source OpenOffice (office suite) and Firefox (web browser) were eventually run on Windows XP

The LiMux/Munich saga was actually successful to a large degree. What happened is that Microsoft put enormous efforts into killing it. High level people like Steve ballmer and Bill Gates made personal visits to Munich officials to win them back, Microsoft put a headquarters in Bavaria, and there were huge concessions. It's about as far as you can get from the image of empty promises and no action.
