I might buy that if someone actually raised their arms straight up and hit the arm there may not be a foul. However if they do anything but raise their hands or arms vertically would still be a foul.

Well, that sure isn't a monkeywrench. All Rule 10-6-1 is doing is repeating the exact same concepts that are contained in Rule 4-44. It's legal to put your arms straight up (vertically) when rebounding. If they aren't straight up, of course there could be a foul called on that person.
