The Belle II software was developed as closed source. As several HEP experiments released their code to the public, the topic of open source software was also discussed within the Belle II collaboration. A task force analyzed advantages and disadvantages and proposed a policy which was adopted by the collaboration in 2020. The Belle II offline software was then released under an open source license on github in 2021. In this contribution we will review the technical, social, and political challenges that had to be overcome for the publication of the Belle II software and take a look at the current status and prospects.
