Mostly because I don't trust that the software they (Comcast et al.) are using to enable this is going to actually: - Always and correctly not be seen as MY traffic - Prevent a jump from the public to my private LAN - Not leave me exposed in some previously unimagined way - Slow down my personal internet experience In the past the Comcast WiFi hardware was particularly prone to not handling a lot of WiFi clients very well. Additionally, I don't want to run their WiFi, I have Ubiquiti gear I'd rather use. Also, I don't want to pay them $x a month to rent the hardware. Finally, even if I feel the probability is near zero and I've got nothing to hide, I still don't want to add just one more way I can possibly get screwed.
