I mean seriously. This has taken a… very long time, but anyone that has been a long-time linux follower has had no doubts. The determination letter took into effect December 27th, and many linux supporters are probably rejoicing that another chapter in the book closes.
I personally would be curious as to how Microsoft is taking this internally. Remember that there was some contraversy some time ago about how some of the money traced to the SCO group actually came from the Redmond giant.
Linux is definitely here to stay.
