We get no privacy when the only server rug pulls.

That issue is down to you. To us.

Convincing people is hard and some might never move away from what they have.

I managed to convince my family and friends, they still use WhatsApp to talk to some people, but otherwise they use Signal.

I did the same what @warm said and I don't even have WhatsApp. If someone needs something from me they have to write on Signal (or SMS 🤣).

It's because they think AI will make them rich somehow and Signal is just a "boring" chat app.

But to be fair Mail is pretty centralized too nowadays for most people @gmail and @outlook. Of course there are others but my point is that there a a hand full of providers up to a point that it's almost unfeasible to maintain and run you own mailserver because there is a high chance that those large providers will flag your mail as spam because it's rare to see a "wild" mailserver.

Nothing like a mall, and your examples don't affect usability.

I'm pretty sure she couldn't. She would wonder why she couldn't contact anyone from her contact list. Sending individual links to probably hundreds of people without knowing if they use Simplex is completely unfeasible. Signal and WhatsApp you just open the app, immediately see who else uses it and can start texting. No multiple profiles, no meeting to scan QR codes or sending links, which is especially ironic because she would probably send that via Signal or WhatsApp 🤣
