A free license may not require compliance with the license of a nonfree program. Thus, for instance, if a license requires you to comply with the licenses of &ldquo;all the programs you use&rdquo;, in the case of a user that runs nonfree programs this would require compliance with the licenses of those nonfree programs; that makes the license nonfree.
