Yes, and telephone operators are required to give law enforcement enough access in order to track down people who do crimes over the telephone.
Telegram does not do that, and does not shut down the illegal behavior. The problem isn't that illegal stuff happens on Telegram, the problem is that Telegram won't help law enforcement when that illegal behavior is found.

They are not; however, required to prevent certain people on a prescribed government list or criteria from owning or using a telephone or from dialing certain numbers.

So it's not because a "channel is against the law."
"Probably" doesn't cut it. If law enforcement doesn't observe it (as would likely be the case on an E2EE-by-default platform), then there's nothing actionable they can do.
If they do observe it, and the platform owners are responsive to taking down illegal content and/or providing information on the participants, then likely law enforcement is satisfied with that.
you're right. Only they have probably have the fullest data on how much crime is moderated or unmoderated on what messenger, the rest is speculation. He probably just got cocky and overconfident, thinking he can beef with the EU on the same level like Musk or Gates.
