It would work even better. From the linked support page:
"Motion is detected based on the amount of signal disruption taking place between the Xfinity Gateway and your selected WiFi-connected devices, so motion from small pets (around 40 pounds or less) can be filtered out while keeping you notified of large movements more likely to be caused by humans."
With enough signals, gait recognition for example is possible, and those same signals could be corroborated with presence or absence of concomitant device signals to determine if your device is moving with your person, and if not, to then flag this for enhanced monitoring if evasion is suspected.
The point is every single thing I own should be "on my side". My car should not store my location history. My wifi router should not track presence and movement. My printer should not add any watermarks or telltale dots. My stuff should actively make it difficult or impossible for hackers, advertisers, or law enforcement to recover any useful information.
This means, respectively: ensure personal info is stored securely so hackers can recover little. Don't transmit info to remote servers to limit what advertisers get. And just store as little as possible in the first place because this is the legal means to have little to subpoena or discover.
Useful info, when absolutely necessary, should be locked behind a password, as constitutional rights preclude law enforcement from making someone disclose it.
I agree, but that is only one reason. The other reason is to save power (and also RAM, disk space, network bandwidth, time, etc) by omitting unwanted functions. (Some things to actively make it difficult (e.g. encryption, passwords) would use up more power, but since they are not constantly active and are not as many functions, they might still use up less power in total.)
This is magical thinking, because it’s using the legal system to solve a technical and social problem. It’s probably possible to create standards that don’t leak PII and other forms of metadata that are unique. That is probably the only solution going forward to reduce possible interdiction by extralegal third parties. However, Comcast can only be enjoined from doing this legally, and will likely not do anything that isn’t implemented by standards bodies, such as WiFi standards. The fact that these capabilities are available to Comcast corporate is because OEMs that make set top cable receivers and combination cable modem WiFi routers provide these capabilities. I’m not sure if these features are standard or require a special order. Once Comcast has the data, it is available to law enforcement via the Third Party Doctrine, which isn’t going away anytime soon.
when I'm at home, my device is just sitting on the desk. rarely is it in my actual hand being carried with me. also i'm old, so i don't have it in my hand while sitting on the couch or in bed either. that's why my laptop is for. something with a real keyboard and screen and not something that's going to give me scoliosis for hunching over to read all the damn time
