Individual messages can be fully encrypted. But the user has to turn on that function.

For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. 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. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat.
