alt Hacker NewsI'd consider end-to-end encryption to also be table-stakes, at least opportunistically after the first message in each direction. With encryption cached messages are far less harmful (though still leaking very useful metadata), without encryption it seems almost trivial to spy on any communications
E2E encryption probably isn’t enough to protect activists trying to organize. Without doing onion routing where you pre-compute some nodes it in the network that it MUST transit prior to delivery and having them decrypt it until it arrives to the recipient (like Tor) you still leak who’s talking to who.
