Funding remains one of the biggest challenges in sustaining free and open source software. In this interactive workshop, we will use the results of a global survey and interview series start a conversation around how developers, users and maintainers think about money in FOSS and what it means for the future of our ecosystem. During the session we will explore donation campaign best practices from FOSS projects, discuss the role transparency and clear policies play in how funds are handled, and give participants an opportunity to learn, contribute, connect and explore how we can help make FOSS more sustainable.
