Moxie Marlinspike Slams Telegram: Experts Claim Cloud Messenger Stores Chats in Plain Text, FSB Links Cited

Post date: March 3, 2026 · Discovered: April 17, 2026 · 3 posts, 16 comments

Moxie Marlinspike stated Telegram functions as a cloud messenger, suggesting all messages reside in plain text within a database controlled by Telegram. Reports further fuel this alarm, citing alleged ties between the platform and Russia's FSB.

The community split sharply between technical risk assessment and user utility. Advocates like Moxie Marlinspike and XLE argue the platform is inherently unsafe due to its architecture and geopolitical links. Conversely, Eyekaytee notes users treat Telegram not for privacy, but because it simply functions as a superior general chat application. An outlier point was raised by AmanitaCaesarea, criticizing Signal itself for needing phone numbers and using AWS.

The weight of security critique points toward Telegram's centralized control being its biggest flaw. While some acknowledge the platform's functional superiority, the core technical argument—that Telegram's structure compromises true privacy—remains the dominant concern.

Signal Founder Moxie Marlinspike: Telegram is not private. There is nothing private about it. They've done a really amazing job of convincing the world that this is an encrypted messaging app
