Are you joking? There's loads of trivial links. Most obviously: it's stopped (pregnancy, menopause) and therefore so too will stop purchases of certain 'female hygiene products'.
And will be targeted by an avalanche of childbirth-related ads... Isn't this an old story now? We've already seen this happening even before evidence of women's health data being sold to ad companies...
I think even Flo's behaviour is not news, but it is worth distinguishing I think between more organic and generic targeting behaviour based on say searches for health advice or other products, and selling 'first-class' health data as it were which is a much stronger signal and feels more personal.
I can't accept that premise. They'll take any revenue they can get, including reselling that same data to Palantir or to RFK Jr's health department. Did you skip several periods and then suddenly start having them again? Sounds like you've had an illegal abortion. SWAT raid on your home, incoming. And so on.
