you hereby grant Summer a non-exclusive, irrevocable, worldwide, royalty-free license, including the right to sublicense, to use and disclose such comments and suggestions in any manner Summer chooses and to display, perform, copy, have copied, make, have made, use, sell, offer to sell, and otherwise dispose of Summer's and its sublicensees' products and content embodying such comments or suggestions in any manner and via any media Summer chooses, but without reference to the source of such comments or suggestions. No, no I don't. Any chance we could choose how to protect or not our own work? Flickr for instance has a very useful set of licenses to choose from including all rights reserved. I get that this isn't quite like Flickr, but giving up the above rights seems a little too much.
