I'm a bit uncomfortable with the "think of the children" kind of argument.
I don't think stories are evil because it is deleted. That means disappearing texts are also evil in Signal. Just because they are kids doesn't make disappearing content suddenly evil.
Sharing of location is also not evil and it is egregious to invoke a pathological case of a kid sharing a location with a predator to justify the arguments.
If these were really concerns then all these things should be severely restricted for children
1. disappearing messages on whatsapp
2. hell whatsapp itself because it can be used to talk to predators
3. almost all social media like Reddit, X
4. online gaming because it can foster bullying and also predators
