Non-acceptance of the Rule of the shorter term
Because United States law does not recognize the "Rule of the shorter term", meaning content that should be in the public domain in the United States (but is the case in its source country), has to be judged alongside the United States' complicated rules for the public domain, and can potentially not be usable on Wikimedia projects.
