It is wrong to say that it doesn't contain any knowledge even if it is not the primary intent. Incomplete and often deliberately misleading but there are actual gains to it. If you were in Cuba and saw an ad for the zero to sixty time of a mini-van which emphasised cargo space that was better than a hotrod. Pretty much any interaction with reality even if pure lies can contain gleamable knowledge from analysis even if it is "they expect us to believe this crap".
