The discussion revolves around Twitter's new encrypted direct messaging feature, XChat, which has received criticism for not providing better security compared to its predecessor. Users express skepticism about the encryption method being used, highlighting concerns over its real effectiveness, including the lack of forward secrecy and questions about what "Bitcoin style encryption" really means. Many users feel that the platform is inherently unsafe due to its nature and operational model, which they believe favors data harvesting over user privacy. The general sentiment suggests a significant distrust of Twitter as a secure communication platform, and calls to leave the site altogether due to its toxic environment and the handling of user data under its current management.
