Pardon my ignorance here, does this mean that governments approach Wickr and buy licences to use their encrypted messenger? If so, what does Wickr do better than other encrypted messenger apps?
Government has a ton of policy requirements around data retention, audit logging, where their data is stored, who can access it etc, as well as technical requirements for things like encryption algorithms. They also have a requirement to operate on isolated networks.
It is difficult for an ordinary consumer messaging app to meet these requirements. Matrix is really the only competitor.
