alt Hacker NewsPresumably the license would, like practically all open source licenses, be irrevocable. You aren't guaranteed new versions will be issued under the same license (short of a contract saying otherwise, just like every other piece of open source software) but the existing license that did not list you as a jerk can't be revoked...
True, but that's still a risk that adds to the risk of the authors switching the license.
BTW, if the jerk list is tied to the license, if the project had external contributors, they all need to agree to add or remove someone from the list, like any license change…
