I was not kidding. I guess I didn't realize they were selling data with PII, which is shocking. I'm actually surprised Google and Facebook were taking in other-party data that wasn't aggregated, just due to the privacy and perception concerns.

That said, it still seems like a vector that's really problematic compared to gain. My personal anecdote is that my kids both only used Pampers Swaddlers diapers, simply because that's what the hospital gave us as we left - that is what I would see as a brilliant marketing partnership for P&G without risks of invasive perceptions.
