I'm not just making up a cause for worrying about free hotspots...It may have been conspiracy talk but there has been discussion about the ethics behind them before. I think it's worth discussing what people are doing with the power to control people's access to internet, especially when it seems like Comcast is just shoving them into peoples homes. Fact: Once you have a XfinityWIFI added to your device and wifi turned on, you are automatically connecting to these hotspots. Lots of customers don't understand the implication of this, which is that Comcast knows where you are located. Fact: You can see a lot more information about devices connected to the an internet access point if you control the lowest routing layer. Just try hooking up a router into another router, and try seeing the devices connected to the first router on the second. Giving Comcast control of routing the internet connection available on your property is allowing them to see details about devices in the area, which they would not see if they were simply providing you a single connection to a router that you own. Sure, plenty of providers had wifi built into their modems (all those crappy 2WIRE things), but at the very least the customer is able to set a password and control who Comcast is able to see is near their property. With this service it just seems like Comcast is making all it's customer's homes a tracking point for everybody else. Why should customers be able to access the internet at random locations based on where other customers live? Isn't that what a mobile data connection is for? Sure, the more hotspots available the better, I guess, but if comcast wants to provide access to the internet it should create a technology that can do it without using other people's property/land/estate, and without being able to gather useful information about peoples' locations and maybe more detailed device and network traffic information. Also, I don't know much about analyzing a single network interface for internet traffic from multiple users, like what we hear about the NSA doing at major internet hubs, but I assume a lot of work needs to be done to filter through information like that. I admit I don't have enough knowledge/experience/evidence/facts about networking, even though I did study computer engineering, but I will make an assumption (at least educated?) that if you have control over the lowest layer of routing you can get a lot more information about the activities taking place on the clients.
