I see. With matrix rooms it is possible to set permissions in a way that only the owner can send messages in that room. There are also large(-ish) rooms, such as #/room/#matrix:matrix.org with > 30k users, but I think threaded discussions would allow for a functionality that resembles a blog where subscribers can comment on articles. And there is a preview functionality that technically allows users to read public rooms without being subscribed.

Of course Telegram is quite a bit more polished and fun to use than element or other matrix clients so far.
