I see what you're saying... but if you were training people to understand the world of information and disinformation then UFO pictures generated by any number of nutters, conspiracists, genuine sightings or government agencies are all just as relevant.
Knowing that the government might include the history of the UFO 'phenomenon' in lessons doesn't inform anything one way or the other; they presumably also teach about Facebook, buses, and how to order noodles in South East Asia. All equally related in the context of being useful information, nothing more.
If what you mean is that the UFO phenomenon simply is what it is as a result of normal human madness (no government help required) then I agree entirely
