I don't think it's beyond their comprehension to ask: "how can I have a chat system that I personally control?" The rest will be taken care of.
Look at the Amnezia VPN. It's an app that helps you buy a VPS from a range of cloud provides, then sets it up, completely from the phone, as an exit node under user control.
I don't see why a chat server cannot be set up and managed this way. It only takes one dedicated developer to produce.
Now we're having an event when networks would be shedding kids en masse, all at approximately the same time. It the best possible time for switching, when clinging to the old discord / snapchat / other centralized blackbox becomes hard or impossible.
Even considering that one can personally control their own chat service is already a pretty big leap in technical knowledge. Many, many average users don't even know that's an option, nevermind how it's even done.
