Microsoft as a company is about 30 years old. Maybe the execs who are old-timers are just tired of the rat-race and retiring to live on their $millions. Microsoft is less relevant than it was 20 years ago, so perhaps it's less newsworthy that they're bleeding executives. It is well understood that Ballmer is a problem for microsoft, so perhaps the executive exodus is not viewed as surprising enough to be newsworthy. I am interested in the notion of chasing away all worthy replacements as a job retention strategy for Ballmer. There's still the complete outsider, like Gerstner from PepsiCo being hired in to run IBM. But there's also a problem with Microsoft's DNA. Microsoft has never made any money by innovating. Microsoft's method is to follow trends and then outmarket and outspend its competitors, leveraging the huge, stable revenue stream from the Windows franchise. This strategy worked pretty well during the time that software came in a box. It worked long enough to chase away innovators at all levels of Microsoft's management hierarchy. But it's not working on the web. That's because (for instance), while anyone can build a search engine, only one such engine is called "google". The brand is the URL, and it has proven hard to get customers to type in your not-as-familiar-as-the-leader URL. Following doesn't work well in the web era. Once a competitor gets popular, they also have the brand/URL and the critical mass of users. Even if you duplicate all the features of their site, it's way hard to convince their users to switch. It must be near impossible to change a philosophy so deeply wired into your company. It certainly can't happen while the executives who were raised on that philosophy are still leading. So maybe they're leaving because they can't change Microsoft's course, and maybe they're leaving because they know Microsoft's course needs to change.
