I'm struggling to muster much sympathy for this couple, TBH. They chose - nobody forced them - to take their money to an under-regulated industry in an illegally occupied part of the world where international laws are not always observed and other nations don't recognise this territory as legal - so your protections are always going to be a bit precarious. The fertility clinics out there sound like the Wild West. Very lax practices, negligent at best but sounds like it could be worse than that.
A decade or two earlier, if you'd sought IVF with, for instance, the NHS, you might not have any say in the donated sperm at all! You certainly wouldn't get to pick and choose from a list of criteria like eye and hair colour, academic capability, interests, athleticism etc. I'm not saying that it's not important to know that the sperm used doesn't carry a high risk of, eg, genetic disease, but to be able to select body type, eye colour etc seems pretty close to eugenics to me. It's really distasteful. I think these women were conned by social mores in general, and the clinics in particular, into thinking that it was perfectly ok and possible to select all these factors in their sperm, and that by doing so, they'd have children with predictable characteristics. I find that morally questionable, as well as unrealistic (it wouldn't, for instance, limit the chances of one of their IVF-conceived children from having a developmental disorder like severe autism, and I can tell you from personal experience that it's a rather more devastating condition to have than eyes that are the wrong colour
).
But those moral scruples aside, isn't it rather obvious that if you pay well below the market price, for ANYTHING, you should expect less than great service? In this instance, either laxity at the clinic led to repeated mistakes, or actual cold-blooded deception, because procuring sperm closer to the clinic would be a hell of a lot cheaper than procuring it from the other side of Europe and having it correctly stored and couriered on dry ice or whatever it is they have to do.
Obviously it's a really sad fact that paying less will get you less, when you're talking about a baby. But then I don't think we ought to be able to select babies for physical appearance. I get that they wanted the babies to be biologically related to one another but they could have opted to use eggs from just one of them. It's the expecting to be able to wrap it up so neatly - each parent's egg gets used, same sperm donor means siblings are still related - that gets me. Life is messy. They have two beautiful children who are currently healthy, and each child is biologically related to one of the mums. I'd take that!
