Aikido founder a fraud?

See this article. I studied martial tai chi chuan for 7 years with a Master and his top students and the magical stories are bunk. Yes, I experienced great skill via this tradition but not magic. And it was physiologically based that required rigorous training and due diligence. I also taught it for a time and had to defend myself from challengers that had more to do with my skill than with any inherent powers of tai chi over any other martial form. Still, even within that tradition there were quite a few students enamored of the magical stories and myths, generally the less skilled who didn't practice enough to be any good.
