"Rather than creating new repositories, we're contributing directly to history. In collaboration with Jason Scott, the well-known digital archivist of Internet Archive fame, we have officially submitted upstream pull requests to the historical source repositories of Zork I, Zork II, and Zork III. Those pull requests add a clear MIT LICENSE and formally document the open-source grant," says the announcement co-written by Stacy Hafner (director of the OSPO at Microsoft) and Scott Hanselman (VP of Developer Community at the company).
