> You're not sharing your information with a human. You're sharing it with a business who is tuned to maximize profit. The ROI on dealing with still births for advertising is probably negative.
Considering only the profit aspect (because the ethics, social responsibility, and public opinion aspects have already been addressed elsewhere in this thread and on twitter):
Surely it's a better ROI to have a user than to lose a user. Hence, it makes more sense for e.g. "stillborn" be a trigger word that stops/blocks pregnancy-related ads for X time than for the user to be so brokenhearted by the platform itself that they leave.
Surely it's a better ROI to show relevant ads than offending ads. Hence, it makes more sense to show e-counseling ads to grieving eyes than to show them tragedy-reminder ads.
Honestly, this seems like a no-brainer from any perspective.
