Telegram is known as a privacy-focused secure messaging app because it markets itself that way. However, it is often criticized by security experts, privacy advocates, and people with common sense who can understand why its claims about being privacy-friendly don't make sense.

Telegram would be just wonderful were it being marketed as what it is. It’s a gorgeous mass groupchat system.
Nothing private at all, but for that you get convenience.
And I would like something also private and still fit for mass groupchats, I don’t know, perhaps, instead of encrypting messages for every participant have some kind of rotating symmetric keys for everyone, like with encrypted TV streams, signed by a smaller set of group moderators. That could fulfill the same role and also be peer-to-peer.
But a lot of things exist beyond our imagination, it’s just that for something to be persistent someone needs to make money on it.
