As long as they don't "farm" the fetuses (feti?) it's fine with me.
They have made suggestions to go to poverty stricken countries and get the fetus from the women there by ways of bribing with cash...
I they would have to farm the fetus. Like I said above, it takes 14 days before they have to stop using that cell because of brain development. So if it took them 30+ years to get something out of Adult Stem Cells it's going to take them just as long if not longer tol get information from the embryonic (word?) type stem cells, so that means they will have to go through a lot of different eggs and sperm matches before they find something. And bribing people for their eggs isn't going to be enough to supply them with what they need..

Fuck children, clones ftw.
Well according to the "Wired" magazine when cloning a human only 75% of Nuclear Transfer is succesful, 4% of Cell Division is successful and then 0% for Embryo Transfer/Live Birth success... So overall the cloning of a human is 0% efficient.
Children FTW.
