Apparently a Congressional investigation into buying user browsing data from ISPs without a functional user opt-out process is bad for business. The Associated Press pens a short exploration (postmortem?) of behavioral advertising firm NebuAD, who saw all of their ISP partners run to the hills when the investigation began. Not too surprisingly, NebuAD doesn't appear to be very chatty these days with the media, so it's not clear if they actually have any customers left. The company is developing a new opt-out system that actually works, but under prolonged inquiry by politicians eager to see such services be opt-in, it's not clear they'll survive long enough to implement it.
