Why We Abandoned Matrix: The Dark Truth About User Security and Safety

Matrix protocol has fundamental security and privacy flaws including metadata leakage, admin-in-the-middle vulnerabilities, weak encryption (Megolm), and protocol design issues like append-only architecture and split-brain rooms.

SimpleX offers an alternative with no user identifiers, mandatory end-to-end encryption, private message routing, and no central components. The article advocates migrating from Matrix to SimpleX for better privacy and security.
