The medical profession is positively paleolithic and incredibly patriarchal when it comes to pregnancy. There is no rational sense of weighing risks by probability, instead it's a "you can never be too safe!" attitude. My wife researched this issue heavily during pregnancy, and what really ground her gears were all the people who say "the safest option is to just not drink at all." But the fact of the matter is that these same people continued to engage in incredibly risky behavior like the wife continuing to drive during pregnancy.
Oh, and "BS"? Really? It's from medical science.
In other words, wine glasses are on par with lawn mowers as far as pregnant women are concerned. They know women aren't interested in them.
But this type of marketing is creepy and invasive. No one likes this because we're basically powerless to choose an alternative. My fiance is marketed tampons on Facebook during the correct time of the month. Because of things she bought on a shopper's card. Disturbing. The real impact will be when your rates on all types of insurance are affected by this data. Or when employment decisions are made.

Edit: Worth posting the whole quote (just found it).
“With the pregnancy products, though, we learned that some women react badly,” the executive said. “Then we started mixing in all these ads for things we knew pregnant women would never buy, so the baby ads looked random. We’d put an ad for a lawn mower next to diapers. We’d put a coupon for wineglasses next to infant clothes. That way, it looked like all the products were chosen by chance.
“And we found out that as long as a pregnant woman thinks she hasn’t been spied on, she’ll use the coupons. She just assumes that everyone else on her block got the same mailer for diapers and cribs. As long as we don’t spook her, it works.”
