Steven Sinofsky Had Inadequate Interpersonal Skills
In the corporate environment an executive should have the ability to work with his/her peers. Sinofsky did not. Therefore, he paid the price and MSFT is better positioned to move forward with their new systems. MSFT management put up with Sinofsky's contentious attitude for many years and finally had to purge him for the good of the Corporation. He did not develop Windows 8 in a vacuum and he can be replaced....Bill Gates supported the purging. Anyone who sold their shares because one executive was fired (he was fired) doesn't fully understand how corporations must work.
