In highschool, my friend group of maybe a dozen had an sms group chat. I spent months suggesting that we switch to signal, but to no avail. Eventually, I convinced one person to join, which made it a bit more convincing for another, and then a few more, and so on. Signal is now the primary means of communication for this friend group, showing that change is indeed possible. Keep fighting the good fight until the rise of these alternative platforms becomes inevitable.
