On the other hand, my dad signed up for 23&Me and one day got a ping.. and then a few more... and a few. more. It turns out he had made a "donation" years earlier and apparently the donation was used to make a bunch of IVF which were then born. It was kind of amazing to learn that I had a bunch of half-sisters and brothers around the US. IBD is pretty reliable and it tends to get better over time (hence the late-arriving signal of french ancestry). I don't understand the "lack of transparency" and the accuracy comment you made: they didn't have the knowledge before, so presumably they reported "european" rather than a wrong country?
