I could spend some cognitive effort explaining in concise terms what should bea very obvious reality. But you know how at one point you stop letting some stuff be open for debate, and spend that effort making jokes instead?

E2E or not, as a parent you can always surveil it on-device. Or just don't give the damn phone at all.

yes, because most HNers are already old so none of that applies to them, thus it's either no internet, no phone or you have to have all kinds of spyware watching what your kids (right up until 18) do 24/7

I bet everyone would've loved to live like that when they were younger. right?

This is a sensitive topic, but I need to be straightforward.

If my children were abducted or sexually abused, or sold drugs, I would request the chat logs of my children, and I would expect the service provider to produce them, even if it takes a court order.

I wouldn't feel comfortable with my children using a service that doesn't or cannot cooperate in such cases.

But most importantly, as an engineer not as a parent, when building systems, it is our job to think of edge cases like that, in a manner that even a parent might not. As an engineer we have more resources to think about this stuff, and in a way more responsibility I don't know how someone arrives at an e2ee encrypted kid adjacent app, it might be incompetence, not necessarily malice, but to be honest, it kind of hurts their reputation one way or the other, they would need some kind of lesson learned and grow past such a sensitive mistake
