The expectation of privacy loses it's meaning when the group size grows. It's more likely what you said remains private when you say it in a group of five people than if you say it in a group of 50, 500, 5000, or 500,000 people. IMO supergroups and channels don't need E2EE, normal groups in Telegram definitely do. It's not an all-or-nothing thing. E2EE where expectation of privacy can be assumed from group size isn't a problem.

Also, Signal has no upper group size limit but E2EE would make group with 100,000s a bit sluggish. But that's a problem that reduces with Moore's law.
