I wonder what would have happened if someone tried using antitrust laws to defeat this. Seems like there was a quite alive market for "third-party HDDs compatible with Xbox 360s" and Microsoft effectively tried to monopolize it. Plus, it seems to me like it could have passed the test of the modern Sherman Act interpretation. MS's actions directly reduced output and increased prices.
