Well, I guess it would be nice if we could have some precedent for the claim that downloading copyright protected information is not in itself a breach of copyright.
It makes sense from the point of view that distribution is the act protected by copyright, not the mere act of copying. If that sounds odd to you then that's probably on purpose, There's been plenty of opportunity to rename copyright to authorrights or something similar, but then people might start wondering how keeping something from public domain for 90 years after the author's death could possibly be about protecting the rights of the author.
