The point was that there are plenty of people in the world who would be more than happy to eat free horse meat.
Yes.. and for a while in the 1920s parts of the soviet population ate their own children to avoid starving to death - people do interesting things when desperate, but not all of them are good ideas.
Basically nothing is known about the origins of the horsemeat apart from the fact that it's horse, that portions of it seems have been supplied by the eastern european mafia, that there's absolutely no paperwork for most of it and that testing it shows remains of drugs with enough side effects that they're generally not used in the western world. This (atleast in Denmark) forced manufacturers to recall them before local athourities deemed them unfit for human consumption.
If someone in europe wants to make an informed decision and take the chance then that's perfectly fine, but unloading it on a population that essentially has no choice is unethical even if it will keep them alive for another day.
So even if you want to stick to the default "starving african children" strawman argument I really can't see the benefits - but then again, why stop at the horsemeat? when we're done distributing frozen food in a warm country with notoriously poor infrastructure and very limited electricity I'm sure we can find some other leftovers of dubious origins, poor nutritional value and with possibly dangerous additives to throw their way - maybe some slighly out of date oysters?
