While that's true, this article strikes me as more of an excuse to bash Comcast than an actual harm. In particular, there are no actual names used, no recordings provided, and no fact-checking. This makes me skeptical from the start. But even assuming this really happened, and that it happened the way it was described, and that the guy wasn't proxying other traffic and/or running an exit node, there's still no report of an actual consequence. If the user in question is claiming that returning Comcast's call is a consequence, then please allow me to apologize on behalf of Comcast, with whom I have no affiliation. I am willing to shoulder 100% of the blame and criticism on their behalf.
Likewise, to anyone who has ever returned a phone call of their own free will only to find that the reason for the call was not of a congratulatory or rewarding in nature, I apologize. This includes, but is not limited to, people who were advised to "come in to discuss test results," whose "payments have not yet been received," or whose girlfriend really needs to "talk" over dessert. Life is not always sunshine and unicorns, and I am sorry that you had to go through that! This is a safe place where you can talk about your feelings. Just let it out.
