This isn't warrant-less, it's with a warrant. This isn't really a change the UK, it's the UK trying to adapt to the proliferation of E2E encryption - ten years ago, law enforcement could always access your messages, now the default if you're on whatsapp/iMessage is they can't because E2E is on by default. UK lawmakers aren't happy with a default position of the state being totally incapable of reading messages, no matter what the law says.

It might not be cryptographically sensible, but it is responding to a real change in the strength of the state.
