Chad Whitacre is head of open source at Sentry, an application and performance monitoring software maker that moved to a business source license for its products in 2019, and then to a functional source license in November 2023. Most recently, Chad has been working on a new project called Software Commons over the last six months, with the goal of balancing the user freedom prioritized by open source software with developer sustainability. In this episode, he discusses the tragedy of the commons vs enclosure, open source vs open products, BSL vs FSL and more.
