Telegram founder Pavel Durov has criticized WhatsApp's security in light of a lawsuit alleging that Meta can access users' messages. According to NS3.AI, Durov's comments come despite Telegram facing its own security challenges, such as bugs that allow message interception and vulnerabilities in its encryption protocols. Meanwhile, Elon Musk has promoted XChat as an alternative to WhatsApp, but this has led to fact-checks pointing out several security risks associated with the platform.
