It's actually the exact opposite. Telegram has made design decisions that prevent them from ever being able to provide private messaging by default without radically altering their design and re-writing all of their clients. The Telegram "client" is really the server -- everything happens there, and the client you use is just a view onto the server.

Thank you for pointing that out.

That structure seems enlightening to understanding how Telegram has been able to create clients for so many operating systems in a relatively short time.
