If you’re arguing that it is possible to build a system that uses a server for routing while keeping clients anonymous, then that is the case. However, what we’re talking about here is whether a malicious actor would be able to intentionally harvest metadata about the users. And my point was that since only the people operating the Signal server know what it’s actually doing, it becomes a trust based system. You have to trust that Whisper Systems is a good actor and they’re not harvesting your information.
