Earlier quoted context omitted.
But every ad network ive ever worked with already allows you to define categories of people you specifically don't want to show your ads to. It's on the shopders of the ad creator to set that up though. I did read a comment one time that said the companies might be doing it on purpose, to "reaffirm" you made the right choice going with their product. Not sure how true that is, but it might factor in.
Honestly, it’s a turn off for me; or rather a small annoyance. But if true, it must work for most people if true, though I’m having a hard time imagining people not slightly annoyed at this ad behavior.
And if that is really the case, then I'd argue it's on ad networks like Google and Facebook to find a way to realign incentives here so that what works best or makes the most money isn't annoying to the user (similar to how they are attempting to ban overly obnoxious ads).
