If your friends can’t install a free app and type in their phone number and an auth code (literally takes 30 seconds) to talk to you privately, they aren’t your friends.
(I have no other messengers and have recruited about a hundred people to use Signal, including much of the Vegas cash game poker scene.)
Quality over quantity is important always, but is of utmost importance when it comes to personal associations.
Delete your Meta accounts, find out who your real friends are.
This is a bizarre position that seems to be advocating for family and friend estrangement based on which chat app they use.
Quite the opposite.
You won’t be able to have friends period if all of society opts in to mass warrantless surveillance.
The Signal desktop app is awful. I refuse to use it for this reason alone, because any time I need to write a lot, I switch to a computer because I can write 100 times faster on an actual keyboard.
