I was stating that within the crowd of people that such a tool is targeted at, someone will run a packet sniffer against it. The likelihood of this happening is high. This is a severe disincentive for someone to 'phone home' if they plan to keep making money from said group of people. As soon as someone runs a packet sniffer and finds something suspect, the whole thing falls apart.

But no, you don't have to keep tabs on it, because you don't have to use this tool. If you do choose to use this tool, you can play the probabilities and more than likely be fine.
