Sentry, a company born and bred in the Open Source community, has been exploring ways to balance user freedom with developer sustainability, leading to an "Open Source sustainability crisis." The company has found success with time-delayed licensing, which allows it to preserve commercial advantage while sharing its software's source code under an Open Source license. A research paper by the Open Source Initiative and Open Tech Strategies titled "Delayed Open Source Publication" reveals that this approach has been used since the early days of Open Source, with companies wanting to keep as many advantages of Open Source as possible while preserving commercial advantage. Sentry's experience with time-delayed licensing has allowed it to prevent larger competitors from eating its lunch and preserve its ability to produce products while sharing with the community. The paper concludes that there is a convergence towards a recognizable set of delayed Open Source publication licenses, including the newly launched Functional Source License (FSL).
