I don't think the point here was to actually run these ads. They don't look like they'd drive a lot of conversion, and there's a big risk that quite a few would actually be inaccurate in practice - Facebook's algorithms, while they know a lot about you, can also be quite wrong. But you can't see that in an article like this, and it's far more likely to reach the right people.
