passwords are the last of it, think about women inquiring about abortions in states where they aren't legal. Or people trying to get away from an abusive partner, on and on it goes.
Agree on the "abusive partner" scenario, but regarding abortions, local police already can abuse dragnet orders on Google Maps [1] - even though they promised to auto-delete anything regarding abortion clinics, there are more than enough other ways for police to target pregnant people.
