I doubt that will upset the public the way Signal and Telegram eventually will. Most people, including criminals, struggle with tech. If they want E2EE badly enough, and use one of the big messaging GUI apps they can succeed. If they can only do it via less user-friendly software, they'll need help or to do research, and likely will leave a trail behind them. That is more useful to law enforcement than if they simply had downloaded one of the most popular App Store apps. It's hard for a news story about a CLI utility to gain traction.
