Wow, lots of misunderstandings flying around here!

* People aren't going to be using your internet without paying for it. Once this promotional period is over, ONLY OTHER COMCAST CUSTOMERS will have access. THEY ARE PAYING FOR IT.

* You WILL benefit from this as well, because you will have access to wifi away from home at no extra charge.

* You will not be sued if someone uses this for illegal purposes. Comcast can tell the difference. If someone downloads child porn over "your" router, Comcast will know who did it and you will not be held responsible.

It's possible that they could have done a better job communicating all this, but really, it is a positive development that will not impact your life at all except when it saves you data charges when you're away from home.
