Documented cause
ZAO launched in August 2019 by Momo Inc. subsidiary and went viral overnight with 8M downloads in 48 hours, allowing users to deepfake their faces into movie clips. Within days, China's Ministry of Industry and Information Technology launched an investigation into ZAO's privacy policy which claimed perpetual rights to user biometric data. Momo was forced to revise terms. Apple removed it from the App Store. Public backlash and regulatory pressure killed the product within months.
Lesson
“Viral biometric apps need regulatory clearance before launch, not after going viral.”
