Not selling anything here considering every reasonable solution to this problem is something offered for free, or can be mitigated by a user with FOSS.
Yea totally normal for a majority to use SMS in my country when both platforms send messages through their own encrypted servers. I don’t have this problem, nobody in my family does, so now explain to me why I should use matrix?
Are you aware of man in the middle attacks? Do you think encrypted channels are safe from state actors?
Also most phones don’t even use SMS anymore, and instead go through an encrypted server to make it so you can hide your traffic from your neighbors.
Get with reality, not everybody wants or needs what your selling here.
