Money
I once worked with a woman who was given the task of being the liaison between the users and developers. While the developers were in a single location, the users were spread, quite literally, across each of the fifty United States. During the time in which she held the position issues as they arose were handled swiftly and to everyone's, or so we thought, satisfaction.
Then the time came annual performance reviews. While she did not get release, she received the worse review possible. And, the reason for this bad review? It seems that her manager didn't like the fact that much of her time was taken up by being on the telephone with users.
The majority of reviews from that particular manager were along similar lines that year. The general consensus was that manager wanted to "free-up" bonus money because the manager wanted a new boat.
