The agency cites data sovereignty and avoiding vendor lock-in as key motivations. This pilot involves a portion of their 600 employees, with plans to expand to 15,000 government users across multiple state agencies. The specific open source alternatives haven't been disclosed yet. ## Full article daily.dev links to this article rather than hosting it.

Better late than never. **@shashoto** · 22 upvotes > Open source should be the standard, not the alternative. **@andersgravgaardjensen** · 4 upvotes > As a Dane who has worked a government job, the initiative sounds good in theory. However, these types of projects usually take a very long time to gain traction and be rolled out - if they ever are at all. > > I’m not very confident in their ability to make this work, and my guesstimate is that 80 - 90% of the public AND private sector is heavily tied to the MS-suite. Retraining people into learning new software could potentially be the biggest blocker in this. **@jack\_starborn** · 4 upvotes > I wonder how soon they will revert this decision due to the same problems that always occurs with these transitions. Have they learned from mistake of others? **@doncho** · 2 upvotes > Oh, not again.... ## Similar posts on daily.dev - [Danish government agency to ditch Microsoft software in push for digital independence](https://daily.dev/posts/danish-government-agency-to-ditch-microsoft-software-in-push-for-digital-independence-7ue7famrg) · Hacker News · 1 upvotes · 0 comments - [Schleswig-Holstein waves auf Wiedersehen to Microsoft stack](https://daily.dev/posts/schleswig-holstein-waves-auf-wiedersehen-to-microsoft-stack-b57qpjb1l) · The Register · 0 upvotes · 0 comments --- Tags: [#microsoft](https://daily.dev/tags/microsoft), [#open-source](https://daily.dev/tags/open-source), [#windows](https://daily.dev/tags/windows) [View this post on daily.dev](https://daily.dev/posts/denmark-begins-its-exit-from-microsoft-and-this-is-just-the-start-o4d559oic) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Denmark Begins Its Exit from Microsoft — and This Is Just the Start","url":"https://daily.dev/posts/denmark-begins-its-exit-from-microsoft-and-this-is-just-the-start-o4d559oic","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/denmark-begins-its-exit-from-microsoft-and-this-is-just-the-start-o4d559oic"},"datePublished":"2025-12-18T08:02:41.444Z","dateModified":"2026-03-30T02:18:15.607Z","description":"Denmark's Road Traffic Authority is piloting SIA Open, a government initiative to replace Microsoft Windows and Office applications with open source...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4553213d56b93fd7fa4d15249fbf387c?_a=AQAEulh","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4553213d56b93fd7fa4d15249fbf387c?_a=AQAEulh","isAccessibleForFree":true,"articleSection":"It's Foss","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"It's Foss","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/582e3faed71842bfb9d3840a787d6700","url":"https://daily.dev/sources/itsfoss"},"commentCount":25,"discussionUrl":"https://daily.dev/posts/denmark-begins-its-exit-from-microsoft-and-this-is-just-the-start-o4d559oic","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":250},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":25}],"keywords":"microsoft,open-source,windows","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"It's Foss","item":"https://daily.dev/sources/itsfoss"},{"@type":"ListItem","position":3,"name":"Denmark Begins Its Exit from Microsoft — and This Is Just the Start"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/denmark-begins-its-exit-from-microsoft-and-this-is-just-the-start-o4d559oic","comment":[{"@type":"Comment","text":"Nice to see governments driving the adoption of Open-Source software.
