A tour of the Microsoft open source lab

Microsoft loves the open source community. They absolutely adore the work of the various
flavors of BSD and happily use their work at every opportunity. 

In a perfect world we wouldn't need a GPL, the BSD license would be all that's needed. The
reality is that companies like MS are happy to take the work of others and provide nothing
back, really that's why the GPL exists. Microsoft would never admit publicly that they
couldn't get a working TCP/IP stack until they took the BSD code and you don't see any
gratitude or giving back. But don't doubt for a minute that MS loves open source, just not the
GPL kind.
