Telegram adds ‘delete everywhere’ nuclear option – killing chat history

Telegram has added a feature that lets a user delete messages in one-to-one and/or group private chats, after the fact, and not only from their own inbox. The “delete any message in both ends in any private chat, anytime” feature has been added in an update to version 5.5 of Telegram — which the messaging app bills as offering “more privacy”, among a slate of other updates including search enhancements and more granular controls. Explaining the rational for adding such a nuclear option via a post to his public Telegram channel yesterday, founder Pavel Durov argues the feature is necessary because of the risk of old messages being taken out of context — suggesting the problem is getting worse as the volume of private data stored by chat partners continues to grow exponentially.
