Does he actually claim to be the founder of hapkido or just Sin Moo Hapkido? I have heard people argue that they 'feel that he is the founder of hapkido' as we know it today, but that is different from GM Ji claiming to have founded the art himself.It seems that even though Ji is claiming to be the founder of Hapkido, he is currently only concerned with ranking in Sin Moo, and there are other entities that rank outside of Sin Moo, apparently.
Maybe he did make the claim, which is why I'm asking, though I have never heard that he did so.
