I proposed a question that I thought was worth discussing considering the leaked presentation which highlights the psychological theater orchestrated by our government on a regular basis. Admittedly, I'm not nose-deep in all of the Snowden/Reddit drama either.
1. The moderation is very recent news, and something like this isn't banged out in 24 hours. Likely this has been in the works for a while, before news broke of the Snowden moderation.
2. The mods on subreddits like r/news are different people from the admins of Reddit. Obvious bias within the subreddits, but I have little reason to believe that it's a site-wide conspiracy from the admins rather than controversial decision making from subreddit mods.
Edit: Looks like possibly this story related to the r/news subreddit and not necessarily reddit in general? [1]
