"After Redmond covered itself in glory by opening up the code,
it now looks like it may have acted simply to head off any
potentially embarrassing legal dispute over violation of the GPL.

"As revealed by Stephen Hemminger - a principal engineer with
open-source network vendor Vyatta - a network driver in Microsoft's
Hyper-V used open-source components licensed under the GPL and
statically linked to binary parts. The GPL does not permit the
mixing of closed and open-source elements.
"This story emerged after Hemminger congratulated Microsoft on
its decision to release the driver to GPL. Microsoft announced the
move as part of a release of 20,000 lines of code to the GPL - an
open-source license it has historically hated."
