Causation
Plaintiffs allege WeChat systematically collects user data — including messages, location, contacts, browsing history, and payment information — and shares it with Chinese government entities in violation of CCPA, COPPA, and the Stored Communications Act. Research from Citizen Lab (University of Toronto) documented that WeChat surveils non-China-based accounts and uses content from international users to train censorship algorithms for China-based users. The app collects data even when not actively in use and fails to provide CCPA-mandated opt-out mechanisms.
