Grand jury subpoena for Signal user data
It'd be better, of course, if we didn't rely on Signal not storing all that metadata and instead used a protocol which made it impossible for anyone to be in a position to choose whether or not to store it.  Unfortunately, the protocols that enable truly traffic–analysis-resistant messaging (I believe the Pynchon Gate[1] is currently the best-of-breed) tend to have increased latency and consume greatly-increased bandwidth.<p>I don't really know what the solution is, but I'm very uneasy about the central point of failure Open Whisper Systems is.  Moxie's previous points about the difficulty of upgrading a federated protocol[2] are correct, but I think that despite the difficulty it's important to do.<p>[1] <a href="http://freehaven.net/anonbib/cache/sassaman:wpes2005.pdf" rel="nofollow">http://freehaven.net/anonbib/cache/sassaman:wpes2005.pdf</a><p>[2] <a href="https://whispersystems.org/blog/the-ecosystem-is-moving/" rel="nofollow">https://whispersystems.org/blog/the-ecosystem-is-moving/</a>
