Xfinity using WiFi signals in your house to detect motion

Sure, but you still can use your own hardware if you choose to. And that's all that the original comment you replied to was saying. If you choose to use your own hardware, then Comcast won't have control over it and cannot do this wifi motion detection.

Of course, most people won't do this, but that's besides the point.

> they only have some level of control over DOCSIS modem

they typically issue a modem / router combination unit, and they can control the router and its radios.

Yes, but you can replace that with your own unit they don't have control over.

…and most people don’t. it’s an additional expense, additional work, and frankly not worth the headache for like 80%+ of users.

I used to work in this space, and have first-hand knowledge about the prevalence of third party modems with a sample set of over 100k people. What’s your experience?

Nobody is arguing against that. I fully agree that most people don't. The point was only that you can.
