> this service starts fragmenting some of the privacy guarantees There is no guarantee of privacy with communication between two consumer smartphones. Encrypted Signal-to-Signal messages have always been susceptible to capture on either end, by something like this bridge or a rogue (or non-rogue) app on either end with access to read device notifications. I'm not saying that this service doesn't expose your messages to some additional risk, and should be used cautiously. But it is an illusion that just because the messaging protocol is using end-to-end encryption that the messages can't be intercepted.
