It doesn't look like Session is going to survive. Session is an encrypted messenger that solves for a few problems that Signal still has. First, users do not require a phone number to sign up. Second, the message delivery network is decentralized, meaning there is no one business entity or country to subpoena for user data.
Now, the Session Technology Foundation is asking for $1M in donations to fund the project for 12 months. https://getsession.org/donate (1/n)
