Is this bit-chat or bitch-at?
While that's a clever hybrid, Bitchat is aiming for a truly serverless, local-first experience (especially with the Bluetooth mesh aspect). Radicle’s gossip-based P2P stack mirrors that vision more closely. In this case, Radicle isn't "better" in a vacuum—it's just the right tool for a project that wants to eliminate mediating servers entirely.

EDIT: sorry I felt too bad not to leave an explanation
Tangled: centralised Radicle
