I, at least, managed to get most of my family to switch. I told them it was the only way they'd get pictures and updates of my son. The one small victory I'm satisfied with.

You don't have to say everything on those apps, tho, just do basic stuff and for longer convos request an encrypted chat app.

Currently, I, my entire Family and everyone I know use Signal. And everyone that doesn't want to, can contact me via Matrix or XMPP, which literally no one ever does, even thought I know a lot of IT and CS people. I keep them as options regardless, just to offer them to people.

I mean, there is also phone, SMS and email of course, but people seem to prefer a new messenger over actually contacting me in any of these ways. And then I'm always like "look, you can choose one of countless ways to contact me, if you like none of them, that's a you-problem".

And no, you can’t convince them to switch messager, I tried.

Have you used the gambling addiction and honeypot comparisons?

Or opium smoking in China one?

If somebody makes a functioning NOSTR client similar to Telegram in experience - maybe that will be convenient enough.
