Why might someone want to use something like #SimpleX when #NOSTR DMs exist?
Not rhetorical.

Privacy as is nostr dm activity is public
And in case of compromised keys from either person welp thats that
Nostr's implementation for encrypted DMs - mainly nip04, is a little wonky.
From left-over metadata found in the event's JSON (who talks to what, how long, what time, ...) to the actual encryption (its much different from the megolm method used in Matrix' E2E), there is some stuff to be worked on.
For that reason, SimpleX is different in it's approach. And thus, could be attractive to someone.
That said, I personally wonder why you wouldn't just use Signal then...? But I personally never read the spec of the Signal protocol... So, those are just my thoughts on it :)
Signal requires that you share a telephone number. SimpleX only requires that you share an address identifier, which is not tied to you in any way. And you can use separate addresses for separate people so that you cannot be identified if you’re talking with two buddies. It provides a more anonymous alternative to Signal in a format that approximates Telegram but which has greater security than Telegram.
Nostr is not appropriate for small group chats, and it’s not anonymous (relays can see IP’s if they do desire).
Welp, that's that.
Signal -> SimpleX it is.
TY!
Signal is great if you want to start a group chat amongst friends. But if some of us Anonstriches want to chat about natural rights but wanted to stay unknown to one another, we’d be better suited setting up a group on Simpx. Telegram group chats aren’t really secure, and Telegram has a habit of censoring groups it doesn’t like (RoboSats, of late). Simpx also allows you to manage servers in a way that Signal does not
For what it is worth, I think redundancy is wise. Use SimpleX as the superior option but don't toss out Signal.
Completely forgot about the phone number requirement. Thanks for the reminder!
