I wasn't really commenting on what Apple should or shouldn't be doing, just on the tone of the conversation in this thread. That said...

Apple have a really good, straightforward option: Don't police user-generated content in iOS apps. Or, at the very least not the ones intended specifically for communication. They aren't listening to people's phone calls or reading their messages in search of ToS-breaching content after all.

It simply shouldn't be any of their business what Telegram's users post on Telegram's platform. Telegram should be able to independently make the decision what it wants to permit therein.
