I had a conspiracy theorist tell me one time this is why they removed all the lead paint. It never quite made sense that kids were actually eating lead chips. I know lead is bad for you, maybe a coincidence.

There is a pattern called 'Pica' where kids gnaw on stuff, windows, ledges etc https://en.wikipedia.org/wiki/Pica_(disorder)

And also how many people are currently in the house, right at this moment. Maybe even which rooms of the house those people are in.

WiFi can also be used to detect heartrate and breathing, which can leak additional ad-targeting information related to activity, arousal, or agitation. https://www.mdpi.com/1424-8220/24/7/2111

I am curious if, with the number and quality of signals they can capture from this, how uniquely they can identify individuals and determine things like age, gender, weight, etc. Particularly when analyzed probabalistically with other household level data they likely have.

So use their router, but connect your own to it. Then turn off the WiFi in their equipment

I'm doing the first bit, but I can't turn off the wifi -- only stop broadcasting my "personal" network. And actually, as I went in to make sure that was the case, I saw that broadcasting of my personal network had been forcibly turned back on. Lovely!

That is what should be illegal, for electronic devices (even if rented) to be unable to disable wireless communications, or for a contract to affect the operation of stuff other than wireless communications when the wireless is disabled. It should also be illegal to be unable to disable all power to electric devices (for devices with battery power, that would include that it must be possible to remove the battery, and the method to be documented).

Can't help but imagine a reality where this is widespread and people resort to installing radio reflective curtains/decorations that freely move with slight ambient air currents in an effort to scramble the reflections and make it as hard as they can to measure.

Something like a belly dance belt around the router could also work.

RF-blocking paint exists.

And contrary to popular belief, neither it nor a faraday cage blocks RF. They attenuate it, to varying degrees.

There is still the question of how much the attenuation is and if it can prevent the detection. There is also the issue if you want to receive other radio signals such as AM radio, FM radio, amateur radio, etc.

The solution here shouldn't be technical; it should be legal. If we rely on the technical path, Comcast can achieve the same by how many active IPv6 addresses are in use. Even if you aren't using your phone, the device is going to be constantly pinging services like email, and your ISP can use that to piece together how many people are at home. If we rely on legal protection, then not only Comcast, but all ISPs will…

> The solution here shouldn't be technical; it should be legal. The parent commenter was highlighting that law enforcement can compel them to provide the data. The customer has to opt-in to WiFi motion sensing to have the data tracked. If you see something appear in an app, you should assume law enforcement can compel the company to provide that data. It's not really a surprise. > If we rely on legal protection, then…

“Please accept our new terms of service to continue using your internet connection”

Your honor, they clearly opted in to us spying on absolutely everything they do or think.

> The solution here shouldn't be technical; it should be legal. I disagree. Solutions should be technical whenever possible, because in practice, laws tend to be abused and/or not enforced. Laws also need resources and cooperation to be enforced, and some laws are hard to enforce without creating backdoors or compromising other rights. "ISPs will be prohibited from spying on their customers" doesn't mean ISPs won't s…

It might make it a bit harder to use the information obtained through spying, though. Both is good.
