Perhaps no one should be surprised that the head of Microsoft (NASDAQ:MSFT)'s internet unit left the company. Its bid for Yahoo! (NASDAQ: YHOO) did not exactly work out well. Redmond will probably not have a big online empire to run without the buyout of the portal company.

According to The Wall Street Journal, "Kevin Johnson, 47 years old, will take a job as chief executive of Juniper Networks (NASDAQ: JNPR), a Silicon Valley maker of networking hardware." The new position sounds like a pretty large step down.

As part of the effect of the departure, Microsoft will separate its Windows group from its online operation.

At this point, who would want to run the Microsoft internet division? It now stands as a distant third in the search business. It competes with Yahoo! and AOL in the portal segment. Display advertising growth rates are slowing.

Microsoft chief Steve Ballmer may say otherwise, but his company has lost the online war. There is nothing left that he can do about that. Spending billions of dollars has yet to gain his company any ground. No executive with a brain is going to want the chance to run a fading business.

A memo by a senior Microsoft (NASDAQ: MSFT) executive sets out some of the reasons for the company's bid for Yahoo! (NASDAQ: YHOO). According to The Wall Street Journal (subscription required), "Kevin Johnson, president of Microsoft's Platforms and Services Division, reiterated the Redmond, Wash., software maker's reasons behind its unsolicited offer, writing that a combination would provide a compelling alternative in search and online advertising." The note goes further to indicate that Microsoft values both the Yahoo! brands and the technical skills of its engineers.

Yahoo! should not take the memo seriously. It would be hard to name a company that Microsoft has purchased that still maintains its own brands and independent operations. Bill Gates has said that the software company will put its full engineering skill behind an effort to build better search technology than Google (NASDAQ: GOOG) has. It may be an audacious and arrogant approach to catching the industry leader, but Microsoft has never looked for outside help to solve its most urgent problems.

All Yahoo! shareholders can look for in the generous Microsoft buy-out offer is a good payday. The world's largest software company looks at Yahoo! as a step in advancing its own agenda and nothing more.
