The whole point of fair use is that it allows people to copy things even when the copyright holder doesn't want them to.
For example, if I am writing a criticism of an article, I can quote portions of that article in my criticism, or modify images from the article in order to add my own commentary. Fair use protects against authors who try to exert so much control over their works that it harms the public good.
