Maybe some companies don't view their employees as their exclusive property that they have to be kept under wraps. If you take this idea to its logical conclusion you'd have to ban your employees from using sites like LinkedIn, which make it really easy to find out who works where. Much better to show your employees that they're appreciated at your company, then maybe they'll continue staying because they really like their job, not because you've set up some policy where other companies who might want to hire them can't find out who they are.
