WhatsApp accused Russian authorities of targeting the app due to its commitment to end-to-end encryption, calling it "a private, end-to-end encrypted (app), and defies government attempts to violate people s right to secure communication, which is why Russia is trying to block it from over 100 million Russian people."

The platform vowed to continue efforts to keep encrypted communication accessible—even within Russia—despite attempts to restrict it.

"We will keep doing all we can to make end-to-end encrypted communication available to people everywhere, including in Russia," stated WhatsApp in a statement.

Telegram, for its part, emphasised its proactive stance on content moderation. The service said its moderators are using AI tools to monitor public areas of the platform, removing “millions of pieces of harmful content every day,” including messages promoting sabotage, violence, and fraud.

"Telegram actively combats harmful use of its platform including calls for sabotage or violence and fraud," said Telegram in a statement.

Russia’s media regulator, Roskomnadzor, cited the apps’ refusal to cooperate in fraud and terrorism investigations as justification for the partial ban on calls. The restrictions affect only voice calls; text messaging remains unaffected. Moscow warned that access will only be restored if the platforms comply with local laws—such as opening legal entities in Russia and cooperating fully with law enforcement.

This move forms part of Russia’s broader strategy toward "digital sovereignty"—reducing reliance on foreign tech giants and promoting domestic alternatives.

The government is developing its own messaging platform, MAX, and has expanded powers to block VPNs and online content it deems unlawful. Critics argue these steps are fuelling state censorship and limiting digital freedoms.
