Threads' direct messaging feature is currently available to users 18 and older on Android, iOS, and the web. Initially, it only supports one-on-one conversations. Future updates will allow users to control who can message them, including non-followers. A message request folder, similar to X, is also planned. Threads is developing group messaging and inbox filters. Despite claims of robust privacy, Threads will not support end-to-end encryption for its messaging. A spokesperson confirmed this lack of E2EE, stating Meta will adapt based on user feedback. The author criticizes this decision, deeming it unconscionable for a new messaging platform. They shared an anecdote about using Threads DMs to exchange contact information to move to iMessage. The author also experienced difficulty accessing DMs on the Threads web app, despite reports of its availability. This suggests potential A/B testing or early rollouts affecting user experience.
