"Crap" is a relative term; 41% (many years ago) was still a lot better than putting out an ad in the New York Times. FB ads aren't perfect, but IME they're a lot better than anything else — the only purchases I've made off ads in the last few years have been from targeted IG/FB ads, and quite a few friends have mentioned the same.
Sort of ironic how the Intercept is apparently capable of believing both that:
* FB is completely incompetent at targeting "to the point of being fraudulent," and can't hit the broad side of a barn with a targeted ad buy, and
* FB is filled with malicious targeting geniuses, whose ability to pinpoint target ads to anyone with incredible precision has made a mockery of democracy.
(Disclaimer: I recently left IG, although I didn't work on anything ads-related.)
