Developers who choose to publish their work under a copyleft license are excluded from participating in software that is published under a permissive license.

Forgejo versions starting from v9.0 are now released under the GPL v3+ and earlier Forgejo versions, including v8.0 and v7.0 patch releases remain under the MIT license.
Copyleft means: “if you modify the program and share it, you also have to include the source code for your modifications.”
The owner of the copyright (usually the developers or their employer) can still change the license later.
