True, but there's a difference between 1. your employer having a bunch of information about you and 2. your employer signing up to a ToS with third parties that effectively hands over all your info to them.
Point 2 is probably not unusual but were starting to see (imho) more pernicious attitudes. Examples include the current Windows discussion, where your employer may be perfectly happy to sign (on the employees behalf) that your data be sent off to Microsoft (and used for whatever Microsoft deems 'necessary'). There was also the announcement of Facebook at Work, which I'm sure would be more than happy to cross-correlate the 'work' you with the 'personal' you, in order to 'provide a better service'.
In both these scenarios, I'm sure the company will act to protect itself from exposure, but it's unclear what choices the employees really have.
