Earlier quoted context omitted.
Aaron's interest in the freedom to share information went beyond just 'open access to public documents'. See for example: http://bits.are.notabug.com/ The 'Guerrilla Open Access Manifesto', also, does not limit its sights to just those materials that are traditionally, or commonly understood to be, "public documents", but to the "the world’s entire scientific and cultural heritage". http://pastebin.com/cefxMVAy With…
The whole quote is "The world’s entire scientific and cultural heritage, published over centuries in books and journals...". He then goes on to talk exclusively about academic publishing in the rest of the manifesto. Even the title - "Guerilla Open Access Manifesto" - refers to a very specific movement in favor of freely available ("Open Access") academic journals.
Scientific papers or the even smaller set of 'public documents' were not the whole program, just a useful (and especially moderate and academically respectable) 1st step. The whole program is opposing all "laws that restrict what bits I can put on my website".
As the wordplay joke at the bottom of the "Bits are not a bug" page notes, "Attorney General's Warning: This page advocates advocacy of the violent overthrow of the United States Government."
