Former Microsoft executive says CEO Ballmer culls internal rivals to retain power

(Reuters) - Microsoft Corp Chief Executive Steve Ballmer is not the right leader for the world's largest software company but holds his grip on it by systematically forcing out any rising manager who challenges his authority, claims a former senior executive who has written a book about his time at the company....

Kempin reserves his most pointed criticism for Ballmer.

"Is he a great CEO? I don't think so. Microsoft's board is a lame duck board, has been forever. They hire people to help them administer the company, but not to lead the company. That's the problem," said Kempin.

"They need somebody maybe 35-40 years old, a younger person who understands the Facebook Inc generation and this mobile community. They don't need this guy on stage with this fierce, aggressive look, announcing the next version of Windows and thinking he can score with that."
