The cynic in me agrees with you here - this is likely a way for them to go "oh no, we couldn't see that information, it's *encrypted* so we have no liability, legal or otherwise, to stop any sort of abuse on our platform since we can't see it"
Well, this is why Signal is fine while the Telegram boss is in jail. As long as you haven't done anything illegal (and aren't explicitly trying to enable illegal activity), it's perfectly fine to just say "we can't do this." I'm really for this; being able to inspect users' data should be a liability.
