Aaron Swartz was a technology activist who believed that information should be freely available to everyone. He helped to create RSS, contributed to the creation of Creative Commons, and also helped develop Reddit. He began the movement that led to the stopping of the Congressional bill that would have censored the Internet (SOPA).
If journalists believe that all people need access to information and expression, then it’s easy to see someone like Aaron as an important ally. The pro-journalism organization Free Press saw him that way.
