These are the kind of features that could cause people to lose trust in a company and its products. "Hey Siri" has had problems, but my impression is that they've mostly addressed them, while issues have also come up with Amazon's Alexa, and even more so with Meta's goggles.
I see so many ads where Meta is trying to rehabilitate the perception of the goggles' privacy features. No company wants to fight that battle. It's a waste of resources.
