A good way to spur adoption of strong cryptography and security

Most consumer routers and modems are outdated, and use firmware that's never or rarely updated. It would be trivial to hack into any such devices used by government employees at home and correlate the user to a database to gather additional information on them. Can foreign governments still teach blackmailed government employees how to pass a polygraph? Seems like counterintelligence investigations now need to include labor intensive firmware dumps of routers. Not like the government accomplishes anything good nowadays anyway.
