If so, doesn't that mean that including any warranties for such downstream software (e.g. proprietary) will breach the license?</div><div><br></div><div>I reproduce the license below:</div><div><br></div><div><div>“Revised BSD Licence”/“New BSD License”/”Modified BSD License” (3 clause licence) (1999) Copyright (c) <year>, <copyright holder> All rights reserved.
