Make no mistake, this is 100% going to be Comcast's alternative to more expensive surveillance options a la Flock, or workplace presence sensor arrays.

Xfinity is absolutely collecting (and probably selling) data on the traffic of every device on your network.

They're doing that anyway via the modem. Unless you are tunnelling everything your ISP sees every byte you send.

    You can also get your own modem, but that doesn’t change the fact that yes, you need to use a VPN for any external traffic you don’t want your ISP seeing.

    However, ISP controlled routers provide them direct visibility into your LAN, which they otherwise wouldn’t see. This gives WAY more detailed information about you and your behavior, i.e. the original article.

    By tunnelling, you mean using a VPN?

    Yeah but to clarify, encrypted traffic is still encrypted. They can't see specifics beyond the sites you went to, urls, dns queries, etc... to hide that you'd need a VPN.
