You could always just...not use/buy their products
You could always just...not use/buy their products
If I, random delivery man, walk up to a Nest user's home, and his camera scans my face to compare to the data stored for facial confirmation, that this information is not used/stored by the recognition software?
The system is always on/scanning. It's using my face somehow, and I'm not using or buying their product, I'm just a person going about my day.
Or to a business with a security camera.
And as for the delivery man angle... sure, that may seem like compulsion, but for one thing, the delivery man can always quit his job (especially in an optimally functioning market which will of course increase labor opportunities and will definitely not reduce wages for labor to its marginal production costs), plus eventually they'll have to quit because we're going to automate delivery anyway.
Doorbell cameras give perfectly adequate views of many places other than people's porches.
If Google wants to put a data-collecting robot on the street with a big sign reading "We're scanning your face to sell to advertisers!" there's nothing I can do about it, but at least it's honest.
Google using Nest cameras to scan the activities of people just walking down a nearby street is not cool.
