Yet, Signal leaks the exact same metadata, if one serves an NSL to OWS.
In a way, Moxie's argument (don't tie things to phone numbers, don't use a centralized system for message transport) is exactly why Signal itself is so problematic.

I'm not going to rely on the US government adhering to its own laws when they've shown they won't do exactly that.
Instead, cryptography is supposed to prevent OWS from even being able to implement a backdoor.
Telcos, on the other hand, are usually based in the country in which they do business (and often have separate businesses in each country, e.g. Vodafone). As we've seen many times, it's pretty easy to get them to cooperate (voluntarily or by law). Much easier to get all the metadata you need that way.
