Hmm.. so the public channel is decentralized but the private channel is not.
There is actually a technical solution to that then. Use the public channel to send/receive private messages. Every could publish a public key. Then everyone could send private messages to everyone by encrypting them with the public key of the receiver and sending them over the public channel.
Shall we try it? My public key:
-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----
You can send me a private message by encrypting it here:https://anycript.com/crypto/rsa
And then pasting the encrypted version into a reply to this comment :)
Paste my private keys into a form control on the web? What could go wrong?
Although I enjoy the public key/private key ideas, If you wish to talk encrypted, one of the best ways to do such could be having signal if you don't mind centralization
But if you want decentralization some options i can recommend are matrix,simplex,session etc.
But to be honest, there is a good point that you raise about how to talk decentralized on bluesky
well, one of the ideas that I can think of right now, is that someone can use https://keyoxide.org/ and paste in their public key and also connect both bluesky and matrix and then have the keyoxide as part of something public like a comment
The problem in this is that it becomes tedious and does add more friction to the whole thing but definitely possible.
