If an untargeted Trump ad impression costs $.02, targeting is worth no more than $.01 to the ad buyer. Meanwhile, the information might be worth $.10 to the local DNC or $5 to a prospective employer. The information would need to be laundered for the latter use case, but that's quite doable and economically so. One use and price point doesn't necessarily preclude the other but discriminatory pricing is easy to arbitrage in the information market, so in practice it makes sense to ditch the low value applications in order to fully extract revenue from the high value applications. I wish bad ad targeting meant that this wasn't happening, but wishful thinking doesn't make it so :/
