That's exactly my point -- (editing clarification) that the Copyright Act does not consider this fair use.
From the article you referenced, "A key consideration is the extent to which the use is interpreted as <transformative>, as opposed to merely <derivative>."
These are not parodies, being used for education or being used for critical analysis of the subject.
It doesn't have to be. Parody and education are the situations where you can pretty much use the entire thing... but they're not using the entire thing.
