Claim: FB will track relationships and social groups and make that information accessible to law enforcement. FB is a corporation that needs to make money; surveillance makes them money.
Contention: Actual privacy and security must protect metadata as well as content.
Cwtch by OpenPrivacy aims to minimize metadata exposed by apps used. It’s built on Tor. Challenges: message latency, server reliability & discovery, (online) first contact problem for key exchange.
