To "prove" that Aikido techniques do go against the joint, you would have to document a technique that went against the joint. Ideally the documentation would include Budo or other early works on Aikido. Off hand, I can't think of such a technique.
Hijiate nage, hijishime nage...
As far as 'aiki-jutsu' ... I think we should be carefull in using that term to represent techniques that 'go against the joint' or 'bonebreaking' techniques. The most qualified use of the term 'aiki-jutsu' that I've seen seems to represent just the opposite. Perhaps the term 'aiki-jujutsu' would be more appropriate...
