Documented cause
Google Buzz launched in February 2010 as a social networking layer built directly into Gmail. On day one, it automatically created a public social graph by exposing users' most frequent Gmail contacts as their 'followers' — without explicit consent. This immediately revealed private relationships: therapist-patient connections, domestic abuse survivors' communication networks, infidelity, and sensitive professional contacts were suddenly public. The backlash was immediate and severe. Within a week, Google faced a class action lawsuit and FTC investigation. Google settled the class action for $8.5M and paid $22.5M in FTC fines. Buzz was shut down in December 2011.
Lesson
“Privacy features in social products require adversarial thinking — not just 'what's the happy path' but 'what's the worst thing this feature reveals about a vulnerable user in an adversarial context.' Ship opt-in, not opt-out.”
