Yes, yes, OMG - yes!
I tend to look the other way about how they sell these DNA tests as some sort of "instant genealogy", when its borderline fraud. It gets people to do tests who wouldn't otherwise, which can be downright priceless for some genealogical cases. it can also be life-changing, as people with unknown biological parents find their biological families.
But this shows that it could be life-changing in a BAD way, too, as the unwary take it at face value and make the obvious (but wrong) inferences.
THAT BEING SAID, maybe there really is a NPE going on here, since she says "we've figured out some likely ancestors". That's a tricky business, though, and it's real easy to fool yourself it's imperative to be REALLY careful.
The way you REALLY know that an NPE is going on is if you get a fairly close relative of his tested (like a 1st cousin). Even out to second cousins it's supposed to be certain that you get a match. If a 1st cousin on his dad's side tests (or has been tested) and there's no match, then one or the other has an issue in their biological ancestry.
But if you can already identify 3rd or 4th cousins on various branches of his family, then you already know there's no NPE, and you don't have to do that.
The ethnicity percentages might give you a HINT that something MIGHT be amiss, but beyond that they should be completely ignored. They're - as we like to say here - "for entertainment only".
