Cons
Con It is not decentralized
This makes it vulnerable to attacks or legal actions. Self-hosted solutions with federation can not be taken down without taking down the internet.
Con Uses message mirroring
You phone must be on and connected to the internet for Signal Desktop to work.
Con Servers hosted in the US
A security risk due to National Security letters, which require giving up data to the US state, and making it illegal to disclose that.
Con Can only communicate with people who know your phone number
Signal hasn’t implemented any alternative identifier to connect users without revealing this detail. (Usernames might be coming soon, though!)
