@kkarhan @signalapp @monocles @lauren Very few systems promoted as Signal alternatives match the cryptographic privacy properties (see: ratcheting, etc.) of Signal.

The claims about "located in the USA" and "Cloud Act" are all nonsense because the only threat to Signal users from this is availability (seizure and shutdown of the server infrastructure), not undetected breakage of privacy properties.

There are presently no systems with superior privacy properties to Signal *and* level of functionality on par with what general public expects. There are a lot (like the XMPP stuff, *sigh*, and Matrix) that are worse in both regards. If you're happy with reduced functionality, Cwtch (and possibly some other similar Tor-based systems) or VeilidChat are stronger, but it's gonna be a while before you convince normies to use them, and in the mean time they're still going to be on insecure shit like WhatsApp, FB Messenger, Telegram, etc...
