Unfortunately no I didn't read the article you linked, I still don't see how this device collects any additional data over what is already available for other devices in the Apple ecosystem. Anybody who has used a Mac, iPhone, or iPad has had HD cameras pointed at them.

To clarify, my point with this comment and my first one was never that data collection (and as far as I can tell mass surveillance as well to you?) was okay, rather that I don't see how this device captures any more data on a wearer than the other devices they likely own.
