I was talking to my brother in law about this. His position approximates this article. While I agree this may not be intentional spying (never proven in court ) on Apple’s part they at a minimum did not account for this huge engineering problem on the back end where Siri couldn’t decipher between key words and background noise. Maybe don’t push products that aren’t robust? Especially since this law suit started in 2019 when voice tech was still (still is) in an infancy.
