Overview

• Elon Musk launched audio and video calling on X, which is enabled by default and exposes users' IP addresses to anyone they talk with.
• The calling feature, part of the X app's Messages section, is not end-to-end encrypted, potentially allowing X to listen in on conversations.
• Users can enhance call privacy by adjusting settings in the X app to mask their IP address during calls.
• The feature's default settings allow calls from 'people you follow,' but can be customized to limit who can call users.
• Privacy concerns are especially significant for high-risk users, such as human-rights activists, who may be more vulnerable to dangers from exposed IP addresses.
