I'm old enough to remember the Microsoft of the 90's and early 2000's. I'm not any more scared of them doing Embrace, Extend and Extinguish any more than I am of other large tech behemoths. Understand that altruism performed by any company of that size is entirely driven by profit motives. Don't assume they want to give everyone SSH hugs just because they're nice people now. But that also doesn't mean they're "evil" per se, just doing what makes sense in today's marketplace.
