Nostr is not private, with anyone's public key you can see who they have sent private messages to.
In Venezuela people are being detained for political ideas, it is not something trivial.
Absolute privacy is essential in such cases.

I agree. Here in the UK the govt talk a good game but they're not really watching us. So #nostr is fine for me.
In a country where money is no object in the persecution of dissenters, you need PFS, so you need #Signal, #Simplex, #Threema or maybe #Cwtch and #Tox, once they've been properly audited.
Tox is not recommended. It was audited back in 2017 and critical flaws were found in its encryption implementation. Literally nothing has been done to fix those problems in the past 7 years. Tox is a perfect example of the dangers of "roll your own encryption".
