I remember one of the wiki leaks releases from last year implied that google/Facebook had the capability to shift political opinion by selecting what people are exposed to. When the government does this I think it's actually less harmful because people are aware the government wants to manipulate opinion. The capability to individually tailor propaganda like is already done with advertising is much worse I think.
