Genuine question: is an app like Sphinx Chat that runs over Lightning something that could work? Is it secure and private enough? I seem to recall a time a few months ago when Discord, Twitter, iMessage etc were all experiencing downtime but Sphinx was working.
Seems like it would work, for the threat model of a casual bitcoin user / P2P trader simply trying to operate essentially below the radar.
Perhaps @paul could weigh in on where any concerns might lie.
