This kind of stuff bugs me, but I understand why these companies do it. For the vast majority of users, having this information available and published in a convenient place probably reduces calls to service. And I bet the technical support staff can see all of this information as well.

I remember being surprised that tech support was able to describe all of the devices sitting behind my AT&T U-Verse modem. I have a healthy amount of paranoia from a few years working in network security. After realizing how much access they had, I went out and bought a Buffalo router running DD-WRT and never looked back.
