1. Telegram, a popular messaging app, claims to have around 30 engineers on its team. However, security experts have raised concerns about this, suggesting that it is a red flag for a platform that has over 200 million active users.

2. The article cites cybersecurity experts who argue that a team of 30 engineers is insufficient to properly maintain and secure a platform of Telegram's size and complexity. They suggest that Telegram's claim raises questions about the app's ability to effectively address security vulnerabilities and protect user data.

3. The article also mentions that Telegram has faced criticism in the past for its encryption protocols and its handling of user privacy. The small engineering team is seen as a potential contributing factor to these concerns, as it may limit Telegram's capacity to thoroughly audit and improve its security measures.
