Several major platforms, including Snapchat, Signal Messenger, and Duolingo, experienced an unexpected outage that frustrated users. Elon Musk expressed diminished trust in Signal, prompting a defense from Signal's President, Meredith Whittaker, who highlighted the platform's reputation for privacy and security. Signal's centralized system does not compromise encrypted communications, as it does not retain keys to the encrypted data. Musk is promoting X Chat as a secure alternative in the messaging landscape, with plans to enhance user confidence through a simplified verification process. Signal has faced criticism over operational issues, and Musk's comments suggest he aims to position X Chat as a competitor to Signal and other messaging platforms.
