I'm not sure you appreciate just how useful that demographic information is. They don't just have your name and address, they have that, the quality of hospital you went to (which in the US, says a lot about you) and the fact of a birth.
This economic datum alone is good for about 15 years of highly predictable target marketing. Long after the baby has stopped wetting itself, the data can be sold to other marketers, who are eager to have it because it's predictable that the child will need new clothes every year, attend school around age 4, want toys around birthday and Xmas, and so on and on. It's worth a lot more than some sample packs of toiletries and baby formula.
I appreciate how useful it is to them, but them having it doesn't mean I don't have it. They haven't stolen anything from me, I haven't lost anything, I don't really care if they have those stats.
