Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durovโs position "very weak," and urged concrete improvements. Despite Telegram's origins, its approach to users' security has privacy advocates worried. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. In this regard, Sebi collaborated with the Telecom Regulatory Authority of India (TRAI) to reduce the vulnerability of the securities market to manipulation through misuse of mass communication medium like bulk SMS.
