99% of Snowden's revelations have never been published
several of the existing copies of Snowden's documents have subsequently been destroyed
I also find it depressing that people like Appelbaum are routinely criminalized:
Public speeches made by Appelbaum taking a humorous and provocative tone and with titles like “Sysadmins of the World, Unite!” were interpreted as an attempt to recruit sources and as incitement to steal classified documents. To this day, however, there are no publicly-known charges against Appelbaum or Harrison.
