'Complete digital sovereignty' ... sounds familiar
Schleswig-Holstein, Germany's most northern state, is starting its switch from Microsoft Office to LibreOffice, and is planning to move from Windows to Linux on the 30,000 PCs it uses for local government functions.
Concerns over data security are also front and center in the Minister-President's statement, especially data that may make its way to other countries. Back in 2021, when the transition plans were first being drawn up, the hardware requirements for Windows 11 were also mentioned as a reason to move away from Microsoft.
Saunders noted that "the reasons for switching to Linux and LibreOffice are different today. Back when LiMux started, it was mostly seen as a way to save money. Now the focus is far more on data protection, privacy and security. Consider that the European Data Protection Supervisor (EDPS) recently found that the European Commission's use of Microsoft 365 breaches data protection law for EU institutions and bodies."
This headline comes up every year that it's time for the government to negotiate contracts with Microsoft. Once they get the best price they think they can, they will accept it and issue a news release that "we're staying in Windows after all".
By 2006, the city had started a concerted effort to move away from Microsoft products and onto Linux. Fast forward to 2013 and 80% of all workstations in the government and related organizations were running LiMux. However, Microsoft’s Windows and Office services were still used.
As we reported back in 2017, the government made a controversial decision to abandon open source and return to Windows.
A newly elected government in Munich, Germany has said it will aim to use open source solutions in its offices. In doing so, the government is moving away from Windows and Microsoft Office despite committing to the products several years ago.
LiMux was a project launched by the city of Munich in 2004 in order to replace the software on its desktop computers, migrating from Microsoft Windows to free software based on Linux.[citation needed] By 2012, the city had migrated 12,600 of its 15,500 desktops to LiMux. In November 2017 Munich City Council resolved to reverse the migration and return to Microsoft Windows-based software by 2020.[1][2][3] In May 2020, it was reported that the newly elected politicians in Munich, while not going back to the original plan of migrating to LiMux wholesale, will prefer Free Software for future endeavours.[4]
EDIT: I guess I should have just read the other comment responding to the parent, which mentioned Munich.
The reason Munich switched back to Windows, when users were just fine working with Limux, was a corrupt politician who ordered the return to windows, probably pocketing a hefty bribe in the process.
The article from 2014 explains how this was mostly a political quarrel, with a former administration transitioning away from Microsoft (which as a US corporation has no business in any government administration of another country), and the conservatives pushing (under a "social democrat" mayor, admittedly) to go back to MS against technological advice.
Im Stadtrat hingegen steht den Berichten zufolge eine fraktionsübergreifende Mehrheit hinter LiMux. Bettina Messinger, Sprecherin der SPD-Fraktion für Personal, Verwaltung und IT, sagte Heise Online, dass man keine neue Haltung zu dem Thema habe. Sie bezeichnete die Umstellung auf Linux als „mutige Entscheidung“. Kritische Stimmen und Beschwerden seien im EDV-Bereich nichts Ungewöhnliches. Man müsse LiMux und das Umfeld nun stetig verbessern und nutzerfreundlicher gestalten. Unter anderem sei dafür mehr IT-Personal in der Verwaltung nötig.
Auch die CSU-Fraktion unterstützt LiMux weiter. Deren IT-Experte Otto Seidl nannte Schmidts Kritik „eine sachfremde Einzelmeinung eines Juristen“. Die Grünen warnen Heise zufolge vor einem „teuren Schildbürgerstreich“, sollte die Stadt zu Microsoft zurückkehren. Demnach wollen die Abgeordneten in einer Ausschusssitzung klären, woher die Beschwerden stammen.
In other words: the "manyfold complaints" were an "ad populum" argument without sources and were most likely made up.
