"Releasing Windows under an open-source license would benefit
the platform in two major ways. First, an open-source Windows could
be had for free, which would mean more legitimate Windows seats
around the world and fewer barriers to upgrading to the latest
version of the operating system. The result would be a larger and
more modern network of Windows nodes at which ISVs could target
sales of their Windows applications.
"Second, a move to open-source Windows would inject an enormous
amount of vitality and innovation into the platform, as the legions
of user organizations, vendors and developers now invested in
Windows could take the platform in new directions, the way that a
much smaller community of stakeholders now does--to great
effect--in the Linux community."
