It also has a sentence claiming that the software is not affected by some USA laws. I think this sentence is meaningless without references to any relevant caselaw, and I think we can ignore it, although I am not a lawyer. BTW, this is a 3rd-party mirror of libmagic. The canonical source of libmagic is in the 'file' package.
