Reputation
Telegram is praised for its speed, multi-device support, and powerful features like channels and bots, attracting over 900 million users including communities and businesses. Criticisms include lack of default end-to-end encryption for regular chats (only in secret chats), raising privacy concerns, and past associations with illicit activities due to lax moderation. It maintains a strong developer-friendly image with open API and source code availability.
