The biggest threat to Microsoft is the Open Source movement. Read about leaked halloween papers here. Meanwhile, the Open Source movement continues to be identified with Richard Stallman and his kooky leftist politics. He is forever trying to explain his meaning of the word free.

But Gnu Hurd is just a toy and BSD is already a polished operating system that runs Yahoo and many other big sites. And BSD is more free than Gnu Hurd will ever be.
