Fortunately in at least some parts of the world providing personal data based on use of LinkedIn to a third party like an employer who happened to use other Microsoft products would clearly violate legal data protection rules and potentially land both Microsoft and the employer with expensive penalties. It's not the same situation as an employer providing an IT facility to their own employees so they can do their jobs but then having morally and perhaps legally questionable abilities to perform covert surveillance of how the employees use that facility.
