Tuist, a software development project, aims to become fully open-source while protecting businesses and developers. The challenge lies in balancing freedom with business protection. Some companies use permissive licenses like MIT and Apache, but these don't ensure a healthy balance. Others adopt AGPLv3 or Open Core approaches, which come with litigation risks. In response, Tuist is considering Sentry's Fair Source license concept, particularly the Functional Source License (FSL). This license balances freedom and protection by allowing code usage as long as it doesn't compete with the business. After two years, the code becomes MIT, ensuring continued development.
