Perhaps you need a refresher in Signal Protocol.

Do not be sprouting on about things that you do not understand.

No, they're not. It's a pretty long stretch from IP traffic analysis to "who's talking to whom".

If you're worried about Signal's hosting provider seeing your device's IP address, use a proxy. Personally, I'm not, because there's no trivial way to go from "Here's some IP traffic" to "this human had a conversation with this human".

Court requires "what was said" for evidence as in old telcom CALEA, whereas Signal via sealed sender basically guarantees the "Spirit of CALEA".
