The broader point is that individuals can try all they want to preserve their privacy, but then friends, family and organisations spy on them, often unwittingly, eg when we share with them calendar events or email messages. The only way forward is collective resistance, building alliances and influencing public policy. But it's always been like that with systemic issues.
