Thank you for confirming that fair use is not a right. Second, yes it absolutely concerns derivative works as it is a concept in the domain of copyright. While not every violation of copyright is a derivative work, only derivative works are justified under fair use. For instance, piracy can never be justified under fair use. The new work must be transformative to a significant degree.
This topic on the other hand has nothing to do with fair use as there is no derivative work being created. It also isn't a copyright violation, it's a violation of the DMCA. Specifically it violates the DMCA's provision that prohibits distributing tools used to violate the copyright of other work.
