This video shows Microsoft offering a cake to Linux on its 20th birthday, to move from Microsoft v/s Linux towoards Microsoft and Linux. The video contest by Linux Foundation invited videos to demonstrate impact of Linux on the computing world. I doubt this is from Microsoft. But how does it matter! If someone feels this is one of the impacts of Linux, then there is nothing wrong with it! This is a bit late from the contest perspective, the last date was 2nd July 2011.
As an aside, it would be really fun if this really is from Microsoft, and they are a bit late for the truce 😉
