Yes but if someone went to those lengths they could just use a hidden camera. My fear is not some very unlikely determined person secretly recording my conversation, my fear is giving every single person in the world an easy tool that they will use that can also secretly record conversations. Hidden cameras exist, but there is very little reason to use one in everyday. But giving every single person a thing they have constantly that does this functionality is a real change. The linked article mentions how cameras were banned, but I still dislike cameras and if I see people with one in public taking photos I will avoid them. If those cameras were always out and always pointing at people I would feel very uneasy.
