@ColinTheMathmo Nice quotation! But the context is even better. It was about having cryptographic apps to allow backdoors, which we don't want — for both technological and democratic reasons. Nevertheless, Turnbull's argumentation sounded legit:

“But Mr Turnbull stressed during the press conference that he was asking for the companies to work with the Government to change their current systems.
‘I am not going to get into hypotheticals. The important thing is to recognise the challenge and call on the companies for assistance. I am sure they know morally they should. Morally they should. They have to face up to their responsibility. They can’t just wash their hands of it and say it’s got nothing to do with us.’”
