Perhaps the most interesting -- and, in retrospect, obvious -- point Marcus makes is that AT&T customers aren't the only ones apparently being tapped. 'Transit' traffic originating with one ISP and destined for another is also being sniffed if it crosses AT&T's network. Ironically, because the taps are installed at the point at which that network connects to the rest of the world, the safest web surfers are AT&T subscribers visiting websites hosted on AT&T's network. Their traffic doesn't pass through the splitters.
