> They should just have no DM feature at all, then; make all messages publicly visible.

This makes no sense.

I can discuss something in a bar which is not a very private conversation, I wouldn't care if someone else hear what I'm saying. But I also don't want someone to record it and post it on the internet to be seen by the whole world.

Privacy is not just boolean you toggle somewhere.

Ah, but you see, soon TikTok will allow parents to spy on their children's DMs, and parents will love this.

I fail to see the link between private conversations/DM and E2EE.

To quote a comment I made some time ago:

- You can call your service e2e encrypted even if every client has the same key bundled into the binary, and rotate it from time to time when it's reversed.

- You can call your service e2e encrypted even if you have a server that stores and pushes client keys. That is how you could access your message history on multiple devices.

- You can call your service e2e encrypted and just retrieve or push client keys at will whenever you get a government request.

E2EE only prevents naive middlemen from reading your messages.

> DMs are akin to private conversations in real life

There are parents out there who would record and AI-analyze every single private conversation their kids have if only the technology enabled it.

You could have reasonable legal system where privacy is guaranteed. But you do not need end to end encryption for that to be thing. It really is orthogonal issue.

Sure, however kids these days often can't socialize irl - should kids be isolated from friends because they're unable to have any private conversations at all?

During times in which I was unable to socialize irl (eg school holidays), and unable to talk to my friends online, I can confirm that the isolation was not good for my mental health.
