I see iMessage and Discord as n-to-n communication - anyone can speak to anyone else typically.

I assume by default that people who want large 1-to-n communication are not interested in actual social activity but rather broadcasting, selling, or proselytizing. They want a podium, or a parasocial Twitter feed-like experience where the speaker can have their say, and the people can comment and either get ignored or immediately countered by trolls or acolytes. The television age's version of this in the 90's was called "Jerry Springer." This is not social.
