Roskomnadzor, Russia's media regulator, has warned WhatsApp that it could be blocked unless it complies with local laws, citing concerns about the platform's use for terrorist activities and fraud. The agency highlighted WhatsApp's end-to-end encryption as an obstacle for law enforcement. Since August, Roskomnadzor has implemented gradual restrictions, including blocking voice calls and instructing telecom operators to stop text message verifications for new users, with a complete ban possible if compliance is not met. The regulator has suggested users switch to domestic alternatives, such as the state-backed MAX messaging app. WhatsApp has around 97 million users in Russia and has faced increasing scrutiny amid a broader crackdown on foreign messaging services. The company has reiterated its commitment to end-to-end encryption but has not publicly responded to Roskomnadzor's latest threats.
