This happened at a place where I worked years ago, but not as 'on purpose.' We were a large company where most pieces depended on other pieces, and everything was fine - until a new CEO came in who started holding the numbers of each BU under a microscope. This led to each department trying to bill other departments as an enterprise customer, who then retaliated, which then led to internal departments threatening to go to competitors who charged less for the same service. Kinda stupid how that all works - on paper it would have made a few departments look better if they used a bottom barrel competitor, but in reality the company would have bled millions of dollars as a whole...all because one rather large BU wanted to goose its numbers.
