The title is a bit misleading.
The story is about unauthorized connections Vista makes. The story is incomplete. The detection of connections is not done with any rigor and nowhere does it say the installation of Vista that is tested is pristine, so there is a LOT of room for error with no attempt to minimize it at all. Even so; I find this alarming and think it needs desperately to be checked out.
Make up your own mind on this one (as if you wouldn't anyway) and it might well be time to check out on your own.
