Oddbean new post about login | logout Session ditched their Monero based tech for an erc-20 token. And you can discuss it on their Discord channel. Does not make the messenger itself less private, but switching to solarpunk technologies in the backend is not a good sign.
I'm not using Session much, among the smaller messengers, most of my friends prefer SimpleX, although Signal and Matrix are still winning by a wide margin. I did a comparison of the messengers: https://juraj.bednar.io/en/blog-en/2022/05/03/encrypted-messengers-comparison/
"A few positive things about Signal. The applications are open-source" It is not true! You cannot reproduce Signal build.
you mean as the blockchain? because session nodes required staked OXEN which was monero based. you mean they switched token chains completely? That would require a rewrite of the nodes as well.
