How Far is Microsoft™ Prepared to Go?

This morning I am stunned by the gap between these two statements:

"i’m is a new initiative from Windows Live Messenger™. Every time you start a conversation using i’m, Microsoft shares a portion of the program's advertising revenue with some of the world's most effective organizations dedicated to social causes. We've set no cap on the amount we'll donate to each organization. The sky's the limit." Windows Live Messenger™

"Microsoft claims that the open-source movement, powered mostly by Linux, infringes on some 235 of its patents, and the company is taking action." How Far is Microsoft™ Prepared to Go?

Is not open source software a social cause???? I met recently with two artists from South Africa who said that access to resources was one of two of the greatest challenge to diversifying their artistic praxis, the other being conservative opinions. In the pending actions of Microsoft™ we see both restriction of access and enforcement of a particular set for solving the problems. Traditional charity organizations (including the World Health Organization, the Rockefeller Foundation, Unicef, pharmaceutical companies and the World Bank) are the benificiaries of the Microsoft™ billions. Sure there is good to be made from the work of such bodies but why cannot open source intiatives be part of such a solution?
