actually not every toolbar installs itself without asking, and not every toolbar that can send information over the internet does this without authorisation or without informing the user that it will do this. So to claim every toolbar that sends information is unauthorized is a bit too harsh.

How about the firefox webdeveloper toolbar for instance? it does not send information to 3rd parties, except maybe for code validation, but that is something you have to activate yourself, so it wont send anything without your explicit say so. and it doesnt install itself either..
