The fact that this code is not current is extremely surprising, actually. It's GPLV3-licensed, so my somewhat uninformed expectation is that MSNBC would be obligated to open-source any derivative works? Unless they did a complete rewrite of the codebase at some point. I created a petition asking MSNBC to open-source the latest codebase and also release the user-generated content to the public domain: https://www.chan…
From GPLV3: "One of the fundamental requirements of the GPL is that when you distribute object code to users, you must also provide them with a way to get the source." Presumably MSNBC didn't distribute object code to users, in which case they have no obligation to open-source any derivative work.
MSNBC really screwed the pooch on this one, from their initial "open source" via zipfile, to the zero-day shutdown. Not what the Knight Foundation intended to fund with their open source requirements.
