Precisely. The intent of those weilding such a weapon is almost an afterthought.

Take as an example, Wikipedia in its most basic form. As a source of knowledge, it is open to subversion of fact and historical reference. Supposing one were to edit the page concerning the line of succession of Roman Emporers and rearranged them to be out of proper chonological order. Even if this false blueprint existed for only a day, how many people around the world would have absorbed this false data and left with a false understanding of something relatively insignificant as the order of succession of Roman Emporers. How many different strands of the causal web will those false beliefs touch throughout the lifetime of the person harboring them? If we extrapolate this into a systemic problem of truth value and design an information system with orders of magnitude beyond the basic flat reference of a Wikipedia...the possibilities for corruption and dissemination of false data becomes unimaginable. A trustless system of information in the wrong hands would be indistinguishable from a God.
