The Olympics, while wonderful, are nothing more than entertainment, so the ethical considerations of "should we or should we not do X" are typically pretty much inconsequential. The ramifications of a runner setting a new record are, in the grand scheme of things, pretty much null.

The ramifications of the average human being able to learn more in less time are relatively gigantic. So gigantic, in fact, that I think they dwarf what small social-inequity considerations are raised (if it can really be done for a $90 kit right off the bat, then just wait until economies of scale kick in).
