> Subject to applicable law, Comcast may disclose information generated by your WiFi Motion to third parties without further notice to you in connection with any law enforcement investigation or proceeding, any dispute to which Comcast is a party, or pursuant to a court order or subpoena.

Sounds like, at least in some limited circumstances (using the provided WiFi AP, having this feature turned on, etc), ISPs are going to be able to tell law enforcement/courts whether anyone was home at a certain time or not.

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.

One takeaway from this is that there's a strong privacy case for disabling the built-in wireless network from your ISP-provided modem/router and using your own, to reduce the number of ways that your ISP can surveil you.

That’s always a good idea, but they’ll still be able to tell when someone is home because the outbound internet traffic will increase.

And don’t forget to set your DNS to a non-ISP resolver.

This is piled on top of the existing strong case for all Comcast wifi equipment being hot garbage. If some confluence of poor regulations has led you to being stuck with Comcast, the least you can do for yourself is get your own DOCSIS modem and routers and access points that you control.

Even better, don't use the Comcast router at all. It's a rip off anyway
