I wish more people were capable of realizing how this surveillance can be abused in ways that aren't stated overtly in the patents.
The problem isn't the stated purpose of the devices, but rather who gets to use the information.
Protip: it isn't that nice boy next door that mows your lawn. It's the guys that ship heroin into the country sewn into the abdominal cavities of war casualties so they can hook your kids on it.
They're on the internet, and they have lots of money to buy data with - or worse, to hire black hat hackers to directly surveil you with these devices.
They don't care about whether they have your authorization or not. They don't abide by EULAs, privacy policies, or any laws whatsoever. Their only concern is power, and they want to have as much power as they can get over as many people as possible.
These devices are their means of gaining power over you, your kids, your money, and the whole damn world.
Thanks!
As long as people are making money nobody cares. Anything that increases sales is good, marketing research is protected under confidentiality by cooperate personhood legal arguments.
If you buy products with the potential for privacy abuse you deserve it and don't expect you will be treated equally to the cooperate personality that conducts this abuse in a court of law even if you have the money for a decent legal advocate and could prove your case.
