the fine print

I noticed that, at some point, someone has sold my chapbook on Amazon. (It wasn't the publisher, as they boycott mass media. As one friend put it, "that'll really stick it to 'em.") Amazon makes it easy enough for me to sell my own copies, so I started to go through the process.

Then I read the "Agreement" that you sign. Below is the license section (bolding mine)

You grant us a royalty-free, non-exclusive, worldwide, perpetual, irrevocable right and license to use, reproduce, perform, display, distribute, adapt, modify, re-format, create derivative works of, and otherwise commercially or non-commercially exploit in any manner, any and all of Your Materials, and to sublicense the foregoing rights to our affiliates and operators of Amazon Associated Properties; provided, however, that we will not alter any of Your Trademarks from the form provided by you (except to re-size trademarks to the extent necessary for presentation, so long as the relative proportions of such trademarks remain the same) and will comply with your removal requests as to specific uses of Your Trademarks (provided you are unable to do so using standard functionality made available to you via the Amazon Site or Services); provided further, however, that nothing in this Agreement will prevent or impair our right to use Your Materials without your consent to the extent that such use is allowable without a license from you or your affiliates under applicable law (e.g., fair use under United States copyright law, referential use under trademark law, or valid license from a third party).

Anyone else find this super scary? I can't quite make out what it's saying.
