The origin of a clone, at least using the current technology, does not involve sperm cells at all. In the few successful attempts at cloning animals, scientists have removed the nucleus of an egg cell from one animal (Animal A) and replaced the nucleus with the nucleus from a cell from another animal (Animal B). The resulting embryo is then implanted into the uterus of a female animal of that species (Animal C). When the clone is born, it is a genetic copy of Animal B.

I guess, in my mind, it's more or less the owners saying, "okay, well we screwed up gelding GT....now...is there any way we can 'breed' GT by making a clone?" AKA "How can we continue to make money off of GT?"
Don't get me wrong, I think it'd be great if this colt could produce great offspring since he's the genetic copy of GT, but it also seems a little greedy.
It's ok to breed him if he was never gelded, but spending a ton of money to get sperm from a clone that may not work out is greedy?
