That was Bridgefy that required initial online access to setup. Briar doesn't and never has.

Traceability of Briar users, if not the actual content, is certainly potentially worse than something like what Bitchat claims (don't use Bitchat it's provably not secure or private at all) with it's traffic obfuscation and multihop. However, the lack of multihop also makes it less promiscuous, so someone would have to be monitoring when you came in contact with the transfer source or destination, unlike multihop that just broadcasts to anyone so they can hopefully relay it.
