Tarpit Messaging only works once everyone you know is already on it — that's the whole moat.

A messaging app's value is the people already on it, not the software. WhatsApp and iMessage own the network and run closed protocols, and Apple actively blocks reverse-engineered clients — Beeper Mini was shut down within days. A better messenger with no users is worthless.

Moat: a network effect — worthless without the crowd · platform risk: high · why: WhatsApp/iMessage are closed protocols · Apple killed Beeper Mini in days (Dec 2023) · direct network effect = zero value below critical mass
