Nerval's Lobster writes "When Steven Sinofsky stepped down as head of Microsoft's Windows division earlier this week, multiple publications cited friction with other executives as the primary reason behind the departure. Whether or not that's the case—neither Sinofsky nor Microsoft has offered an official explanation, aside from the usual platitudes—someone with connections to Microsoft is claiming that Sinofsky's departure stemmed from a failed attempt to bring additional parts of the company under his control. 'Steven had apparently lost recent battles to bring both Windows Phone and the Developer Division under his control,' Hal Berenson, president of consulting group True Mountain Group and a former Microsoft executive, wrote in a Nov. 13 blog posting. 'I suspect that he saw those [losses] both as a roadblock to where he wanted to take Windows over the next few years, and a clear indication that his political power within Microsoft had peaked.' The departure, he added, was the 'outgrowth of conflict.' Berenson's claim was enough to draw Sinofsky himself into the discussion. In the comments section below the posting, Sinofsky left a short note suggesting that rumors of a multi-product takeover were, frankly, malarkey."
