Microsoft contributed at last

If you ca not beat them, join them. This saying looks pretty old but can we regard  Microsoft followed it when at last they contributed on Linux kernel construct. Linux foundation announced Microsoft as the 17th  contributor to the construction of their kernel. I think from now on we will see more collaborations between these two. I remember that Microsoft's Steve bellmer once called Linux a cancer, I guess now the cancer has been cured. No more viruses for Windows
