Munich - one of the biggest cities in Germany - has migrated its infrastructure to Linux, a project called Limux. There was a lot of discussion surrounding this project. In the discussion also often costs are discussed. The different sides argue how much the transition to Linux and Open Source Software costs. See for example this news in german (I couldn't find something in english, sorry). There is discussed whether the project costs 23 million or 61 million Euro.My question is: How can the usage of Open Source Software cost so much? Isn't the software free for download? Which costs are involved in using Open Source Software/Free Software?
How can it be that using open source software involves costs?
