Apple and Microsoft under threat of Russian blocking Roskomandzor has included Apple and Microsoft in its registry, which requires the companies to store user data and correspondence in Russia and provide information to authorities upon request. If these requirements are not met, companies may face a ban based on a court decision. The oddity is that Apple's iMessage service uses end-to-end encryption, which is why the company does not have access to the content of secure correspondence. This may make it difficult to comply with Russian legislation.
