Please correct me if I'm mistaken but companies using Google services such as GMail and Docs use them through Google Apps which isn't subject to advertising like the public versions of these services.
You're missing the point--when the switchover occurs the ads accompanying regular google search will pull upon a profile which includes your GMail/Google Docs accounts as well.
Data from Google's enterprise products are not included in your ad profile. I can't imagine they will change that, or they will see a mass exodus from their platform. Just because something shows up in your (March 1st) search results doesn't mean it was used in generating the ad next to it.

I have observed people tend to accept vendor lock in. Particularly when the migration costs are high.
Likewise, the cost of lost enterprise accounts would have to offset the revenue gained from mining the data...assuming of course that Google isn't already mining enterprise data.
