It feels rather more than a little bit creepy to realize that Comcast et al, and thus the US government (if you live there), laundered through 3rd party data brokers, knows if you're sleeping and knows if you're awake. Knows if you've been bad or good, for ICE/ATF/DEA/SEC's sake.
Comcast is late to the party, then. AT&T has been selling your information for decades. And your mobile provider can track you anyplace that there's a cell-signal, potentially even outside the country.
