I shifted my family and close friends to signal. people who trust me and value my friendship easily made a signal account just because I told them that its better than whatsapp.
The rest, haven’t, and I don’t really care about them, this has allowed me to stay in touch with people who are closer to me in a more efficient way and cut down on unnecessary chatting and checking my whatsapp, which has become a lite version of facebook with a whole status and channels tab.
like @Onscreen5341 said, on signal I reply asap, but I don’t check whatsapp more than a few times a day, so if someone is trying to get in touch or wants to be closer friends with me would bring it up and i’ll give them a pep talk…
this works for me
the chats were leaked by someone in the group (afaik) that could be the case for any conversation, the leaks weren’t due to a flaw in signal’s protocol. And if your friends are knowledgeable enough and value privacy, tell them that edward snowden uses signal.
