The creator of Bear, a blogging platform, has changed its license from MIT to a version of copyleft based on the Elastic License, which prohibits providing the software as a hosted or managed service. This decision was made to prevent competitors from forking the project and offering it as a service, which has happened in the past. The creator wants to ensure the platform's longevity and commitment to its users. The new license still allows for other uses of the software, such as learning from the code and auditing its security.
