AT&T's is much more invasive -- it is across all of their telecom platforms (DSL, TV, wireless, wifi, etc). They also will log location information for advertising: http://www.att.com/gen/privacy-policy?pid=2506
If they were to begin network sniffing, they could potentially build powerful user profiles that would be more valuable than Facebook's data (and truly "frictionless"). Your passive internet browsing would start influencing the commercials you see on TV.
