Suppose I want to modify a license. Say I choose the MIT license:
..to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software,...
and I would like to remove publish and add some restrictions.
Then change the name of the license.
Same question about disclaimers and terms of service, for instance, pick the Google terms of service and modify it to adapt to particular needs of a project.
