I've been telling people for ages to not trust ISP provided hardware. Notice the vague language here which means they reserve the right to share private information for anything that might be called an investigation, or for any dispute which includes them (didn't pay your bill?), or a subpoena.
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.
Plus, sharing isn't limited to a court or law enforcemnt agency - they reserve the right to share information with any third party.
This is scary, particularly considering how the current administration wants to weaponize everything they possibly can.
This is what precisely why I willingly pay more to Google for their fiber optic service than AT&T for an equivalent, albeit less expensive, plan: Google readily allows me to use my own equipment. I am voting with my dollars on this one.
Scary, but is it any scarier than the status quo before this feature was implemented? The fidelity of the data, perhaps, but it's more or less been the standard that our footprint where we intersect with a third-party is no longer ours to control.
