@cstross@wandering.shop Here you go: https://www.cornell.edu/copyright.cfm But the contribution seems to be in breach of the submission agreement of arxiv as well: https://info.arxiv.org/help/policies/submission_agreement.html "I [sc. the submitter] have the right to include any third-party materials used in the Work." That doesn't seem to be the case. Maybe that's a more promising route than the DMCA, because it involves publication ethics.
