xFI is, in a nutshell, a way to manage your router remotely from anywhere. No longer do you need access to somebody's PC on the network to gain access to the router, when you can just break into their Comcast account and open all the ports you need to break into their PCs! loving radical, right? The privacy policy is also loving great:
https://www.xfinity.com/support/internet/comcast-web-services-terms-of-service-and-privacy-policy/I'm one of the "select few" who got a new router from Cumcast and it's appalling at how much they overstep their bounds. There's also a "Protected Browsing" feature which filters all network connections to certain safe space websites, meant to "protect you from viruses" and stop you from viewing child abuse websites. No offense to them, their solution for it is great with a sleek app that doesn't stop you from doing anything and looks modern, but Jesus Christ. There's no authentication checking for the router password/username, no bullstuff like that. Once you log into the account, you're pretty much in forever, and you can change all the options you want.
Can't wait for all of my browsing data to be sold. If you're a Comcast customer, this should be enough to push you to use a VPN.
