One thing to consider is that the issue is bigger than Oscar. While the current prosthetics may only level the playing field (or maybe not even that) it's only a matter of time until prosthetic technology does become a big advantage, perhaps more so than PEDs.
Also, another argument is allowing able bodies and disable athletes to compete together is that it has the potential to belittle other paralympians, 99.99% of whom could never dream of competing with the able-bodied but are nonetheless great athletes and competitors in their own sub-category of track.
