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.

by a system with a incentive to keep them in centralized black boxes, yes.

It's never the tech hat's hard, but the networks. If people were able to just jump on a whim a lot of dynamics of modern corruption would fall apart.
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.
