So many things wrong with this: -Comcast provides a device to me and charges mea rental fee then turns around and profits off of it at no benefit to me. The modem even requires batteries which I have to pay to replace for God's sakes. -Legal implications of other users potentially accessing illegal materials over a device located in my home. -The Modem/Router combo supplied by Comcast is a piece of junk, and barely works for home use, let alone handling traffic created by strangers connecting. I can confirm that Comcast does indeed turn this on without your permission. Furthermore, unless you pay attention you may not know that it is even happening. You can't disable it through the router administration either, you have to go through Comcast's website to find the setting and opt out. All in all it's kind of a slap in the face after suffering through years of sub-par service and borderline abusive business practices.
