I don't understand your objection. Disclaiming the rights is a matter of clarification for those who might consume the works in the repo. The archiver is making it explicit that they cannot publish the works under $YOUR_FAVORITE_LICENSE because the works aren't theirs to license. Disclaiming the rights doesn't grant any license nor does it protect the archiver from infringement claims. I don't think there was any suggestion that was the case.
