I have stopped communicating with friends and family who try communicating via insecure apps. I send a response saying I will only read Signal or similar messages from them.
Some think this is a hardline, but my security is important to me, and true friends and family need to respect that.
It's kind of like how my sister is vegan, so when she comes over for dinner, I cook vegan dishes for her. I respect and accommodate her lifestyle choices, and she does likewise by communicating with me via my preferred medium. Conversely, for example, I no longer talk to one cousin because he ignored requests to use a safe messaging app, and that is OK too.
