Mark Pilgrim responds to Microsoft's patent-infringement assault on Linux with a bit of autobiography:

My name is on a software patent. It happened during my brief tenure at IBM.... No one had done this exact thing, in this exact way, for this exact purpose, before we did. The patent was original, it was innovative, and it was still shameful.
UPDATE: There's a good history of Microsoft's war on open-source at Roughly Drafted.
