Their privacy policy contains some interesting stuff about your actual privacy: "Compliance with Laws and Law Enforcement Requests; Protection of Dropbox's Rights". Also, the "Security Overview" page explains that the files are encrypted by themselves after they are uploaded, plus the fact that they manage the encryption keys. Combine that with the previous statement. Dropbox is responsible for what they say. It isn't responsible for what the user understands, or the fact that people don't properly read/understand ToS'es. People that care about their privacy, take measures.
