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.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.[1] http://freehaven.net/anonbib/cache/sassaman:wpes2005.pdf[2] https://whispersystems.org/blog/the-ecosystem-is-moving/
