Telegram CEO Pavel Durov has criticized WhatsApp's end-to-end encryption, labeling it as a 'massive consumer fraud.' According to ChainCatcher, Durov highlighted that approximately 95% of private messages are stored in unencrypted backups on Apple and Google servers.

Durov expressed concerns that this situation poses a risk to user privacy. Despite WhatsApp's claims of using end-to-end encryption for message transmission, the backup mechanism fails to ensure complete encryption of user information. His remarks have sparked industry attention regarding privacy protection measures in mainstream communication applications.
