Snowden is not a paragon of privacy morality one should seek to emulate; his actions are incredibly hypocritical to pretend to care about privacy after invading everyone else’s privacy, then bouncing to a hostile foreign nation.

Instead, a quote like this would do:

Whoever can pierce your privacy can humiliate you and disrupt your relationships at will. No one (except perhaps a tyrant) has a private life that can survive public exposure by hostile directive.
