In this contribution, we show how the evolution of an open source business model requires the adhesion of the community and an alignment of the different stakeholders perspectives. We analyze the ecosystem of a 20-year-old Learning Management System and describe the different steps that led to two forks. Using the Hirschman’s loyalty, voice and exit mechanisms we conclude on recommendations for external contributor’s management and on a discussion on how these mechanisms could be completed for the open source sector with fork and apathy.
