> To keep Signal a free global communication service without spam, we must depart from our totally-open posture and develop one piece of the server in private: a system for detecting and disrupting spam campaigns. Interesting. Matrix solves this problem by not associating a username with a phone number or email address (unless you opt in to). Does anyone have views on if this will work into the future? I'm moved ~90 of my friends onto Matrix (along with plenty of group chats), and most of them quite like the Element [1] app (though there are rough edges on iOS I'm hearing).
