Page "End-user license agreement" Paragraph 5

Some copyright owners use EULAs in an effort to circumvent limitations the applicable copyright law places on their copyrights ( such as the limitations in sections 107-122 of the United States Copyright Act ), or to expand the scope of control over the work into areas for which copyright protection is denied by law ( such as attempting to charge for, regulate or prevent private performances of a work beyond a certain number of performances or beyond a certain period of time ).

Such EULAs are, in essence, efforts to gain control, by contract, over matters upon which copyright law precludes control.
