Governments need it to be solved by a team (either within the government or a vendor company) because it is the non-tech things that are missing from the open source solution: high availability / redundancy, hosting, backups, business continuity, audits, someone to grill when there is a leak.

The people who work in government and banks aren’t incompetent. They are just like you and I but they work within a highly rigid system because if their system isn’t rigid, societies fall. People don’t think rationally during bank runs or when nobody in a country can access public services for weeks at a time. This is the core hazard of Mr. Robot.
