What do i say to my friends to get them to leave? Ive already tried and they won’t.

Sadly this change won’t really affect them so they are not going to care. I’ve wanted to leave for a long time now.

No. Signal encrypts every message on the device itself before sending to Signal servers. You can even confirm this yourself by looking at their github.

Whats app claims they do this but its impossible to confirm. Its extrenemly likely that either they dont encrypt at all or they have the decryption keys.
