So there was no crime before Telegram? These kinds of things won't be used to stop malware or cybercrime anyway. They'll be used even more by those in power to subvert. The criminals will just move to another operating scheme.
Nice knee jerk reaction here (not just you, replies to me in general). We take down malicious domains and servers all the time. What's so special about group chats? As long as there is a proof it's used purely for criminal things and it's technically possible there is no excuse not to take them down.
The same applies in the physical world. Police has no right to enter your house. Except when they have a warrant, because you are already known to be guilty.

Great! This is not an excuse to do nothing. They would use e2e if they were smart anyway. But they don't, because they like telegram and e2e is annoying to use (no channel history etc).
I would argue that difference is that entering my group chat is the same as entering my house to install a listening device. If there is a warrant to tap someone's phone, that is based on probable cause not blanket surveillance. We don't shut down a bar just because some criminals hang out there.
Also, warrants are when there is evidence to suggest guilt. You are not known to be guilty. That is the point of the warrant, to collect more evidence to prove guilt.
