What if the ads for baby products were on advertising outside (or inside) the hospital. Should there be NO advertising for baby products because 1% of pregnancies end in stillbirth?
I'm pretty sure OP is saying, "Hey, tech companies, if you're going to mine my data to figure out I'm pregnant, maybe you should give me some way to tell you that the pregnancy ended in sorrow, and I don't want to see any ads about baby needs."
It's not calling for a ban on baby product ads.
It's saying that force-feeding ads on baby products to someone who has lost their child is awful, and it doesn't seem like a big stretch to let a user say, "I don't have a baby!" in a way that tech companies / advertisers can use, to be more sensitive.
Some advertisers have bought the right to display their ads to people the platform has probably identified as “women having babies soon”.
Does the OP want consideration from the platform or the advertisers?
I feel the OP is venting the feeling that they’ve had a huge personal tragedy yet the world has just kept on going like nothing happened.
