Nobody disputes the value of end to end encryption. That's not the issue.

The problem of encryption is that it changes the relationship between government and individual in a way that has never been seen before. If a person is suspected of committing a crime the police have always had the ability to intercept mail, record calls, search property etc and obtain evidence. They can't do that now.

You can argue the pros/cons of this new world order. What you can't argue against is the natural inclination of many people to simply maintain the status quo.
