Even in WhatsApp which has E2EE they have reporting mechanisms so if someone starts a broadcast channel with the explicit intention of promoting illegal behaviour, it can at least be taken down by reporting. Personal experience and second hand accounts tell us that Telegram was known to mismanage these things in ways that a company of its size and impact cannot ignore.

There’s a lot of false dichotomy in the ongoing discussions here which assumes there’s a binary “control to the gov” or “freedom for all” choice. It’s a spectrum where at the most basic level, a robust process to handle reports of illegal activity should be accepted.
