This is my kept-warm take on Signal.

Signal personal should continue being free. Signal needs to develop a business line for enabling authenticated, private communications to individuals on Signal.

There's at the very least an entire area of secure healthcare messaging which is full of terrible bespoke systems, or just goes over SMS, which would more effectively and with better user experience go over signal (i.e. the ability to send longer messages, encrypted attachments etc.)
