There’s no law in existence that requires them to store metadata or hand anything over to the feds. They have been subpoenaed several times and it always comes out the same: the only data they have is what I detailed above. Even if they DO have it (which they don’t) they don’t provide it, which is effectively the same thing.

It is just enough that this metadata be handled within the computing environment of Amazon. Their refusal for anyone use their own server and federate with “their” (as in captive) users also prevents anyone for using it in any other way…

If you dont see that Signal requires that its users use a strong-selector phone# in order to use the service, there is nothing i can do for you.
