One of the ways that Microsoft is outside Silicon Valley culture is the degree to which a founder and early employees maintain Ownership due to Microsoft's early profitability and decision to avoid significant outside capital and the share dilution which accompanies it.

Quite simply Google could never could never replicate Microsoft's culture because there never was a time when when a large enough fraction of employees had fuck you money. Microsoft's culture is different by virtue of the fact that venture capital has never had much of a say.

Hence a positive vision of "a computer on every desk" rather than a mere admonition to not "be evil".
