Huh? The bot can communicate with me freely as it sees fit. A "conversation" in telegram parlance is not time-limited, it's ongoing once established, so no it's not only inbound. It can awaken and ping me whenever it wants. This can also work if it's added to a group chat.

If you mean it's not outbound as in it can't message arbitrary random users out of nowhere, well yeah, and that's a very desirable trait.
