As far as I can tell, "nodes define their own trust relationships" is true only when considering the protocol at an abstract level, or if you're building the code yourself. As a concrete end user using the Signal client, you don't actually get to define your own trust relationships; the app is just hardcoded to trust a specific list of servers, albeit somewhat protected by SGX. Please correct me if I'm wrong.
